(See the topic Switch-Status Condition in the chapter Procedure Division.)

General Rules for Format 2

  1. ANS85 The literal in the VALUE clause associated with condition-name-1 or condition-name-2 is placed in the conditional variable according to the rules of the VALUE clause (see the section The VALUE Clause.) If more than one literal is specified in the VALUE clause, the conditional variable is set to the value of the first literal that appears in the VALUE clause.

General Rules for Format 3

  1. VSC2MF The sending value represents the address of a data item. If pointer-name-2 is specified, the sending value is the value contained with the data item referenced by pointer-name-2. If ADDRESS OF identifier-2 is specified, the sending value represents the address of identifier-2.

  3. VSC2MF If ADDRESS OF identifier-1 is specified, the sending value is moved to a COBOL system area and the runtime element subsequently operates such that the area of storage referenced by identifier-1 is located at the address represented by the sending value.

    MF Whether or not the link is retained between invocations of a subprogram is dependent on the STICKY-LINKAGE Compiler directive.

General Rules for Format 5

  1. MF Before execution of the SET statement, the value of the data item referenced by pointer-name-3 must represent the address of a data item within a logical record, the original address. After execution of the SET statement, the value of the data item referenced by pointer-name-3 represents the new address. If the original address and the new address do not both lie within the same logical record, (or, for environments in which address space is segmented, within the same segment) then the results of using the value of the data item referenced by pointer-name-3 are undefined.
  2. MF If the UP clause is specified, the new address is formed by adding the number of bytes given by the increment value to the original address.
  3. MF If the DOWN clause is specified, the new address is formed by subtracting the number of bytes given by the increment value from the original address.

General Rules for Format 5

  1. The following steps are repeated for each recurrence of index-name-1 or identifier-5. Each time, the value of index-name-2 or identifier-6 is used as it was at the beginning of the execution of the statement. Any subscripting or indexing associated with identifier-5 is evaluated immediately before the value of that data item is changed.
    1. If index-name-1 is specified, index-name-1 is set to a value causing it to refer to the table element that corresponds in occurrence number to the table element referenced by index-name-2, identifier-6, or integer-2. If identifier-6 references an index data item, or if index-name-2 is related to the same table as index-name-1, no conversion takes place.
    2. If identifier-5 references an index data item, it can be set equal to either the contents of index-name-2 or identifier-6 where identifier-6 also references an index item; no conversion takes place in either case.
    3. If identifier-5 does not reference an index data item, it can be set only to an occurrence number that corresponds to the value of index-name-2. Neither identifier-6 nor integer-2 can be used in this case.
  2. The following table represents the validity of various operand combinations in the SET statement. The general rule reference indicates the applicable general rule.
    Table 1. SET Index Statement Valid Operand Combinations
    Sending Item Receiving Item
    Integer Data Item Index-Name Index Data Item
    Integer Literal No/11c Valid/11a No/11b
    Integer Data Item No/11c Valid/11a No/11b
    Index-Name Valid/11c Valid/11a Valid/11b1
    Index Data Item No/11c Valid/11a1 Valid/11b1

    1 = No conversion takes place.

General Rules for Formats 6 and 7

  1. Index-names are associated with a given table by being specified in the INDEXED BY phrase of the OCCURS clause for that table.
  2. If index-name-1 is specified, the value of the index after the execution of the SET statement must correspond to an occurrence number of an element in the table associated with index-name-1. The value of the index associated with an index-name after the execution of a PERFORM or SEARCH statement may be set to an occurrence number that is outside the range of its associated table. (See the topic The PERFORM Statement and the topic The SEARCH Statement.)

    If index-name-2 is specified, the value of the index before the execution of the SET statement must correspond to an occurrence number of an element in the table associated with index-name-1.

    If index-name-3 is specified, the value of the index both before and after the execution of the SET statement must correspond to an occurrence number of an element in the table associated with index-name-3.

General Rules for Format 7

  1. The contents of index-name-3 are incremented (UP BY) or decremented (DOWN BY) by a value that corresponds to the number of occurrences represented by the value of integer-3 or the data item referenced by identifier-7; thereafter, the process is repeated for each recurrence of index-name-3. For each repetition, the value of the data item referenced by identifier-7 is used as it was at the beginning of the execution of the statement.

General Rules for Format 8

  1. MF The sending value represents the address of the start of a procedure within a COBOL or non-COBOL program.
  2. MF The sending value is moved to the data item referenced by procedure-pointer-name-1.
  3. MF If procedure-pointer-name-2 is specified, the sending value is the value contained within the data item referenced by procedure-pointer-name-2.
  4. MF Literal-1 or the content of the data item referenced by identifier-8 is the name of the referenced procedure. If the referenced procedure is a COBOL procedure, the name of the referenced procedure must contain the program-name contained in the Program-ID paragraph of the referenced program or the entry-name contained in the ENTRY statement of the referenced procedure.

    If the program being called is not a COBOL program, the rules for the formation of the program or procedure name are given in your COBOL system documentation on interfacing.

    If the referenced procedure has been previously made available and remains available at the time of execution of the SET statement, then the sending value represents the address of the referenced procedure.

    If the referenced procedure is not available at the time of execution of the SET statement, then the sending value represents the address of a COBOL system error procedure.

General Rules for Format 9

  1. ISO2002MF If identifier-10 is an object reference, a reference to the object identified by identifier-10 is placed into each data item referenced by identifier-9 in the order specified.
  2. ISO2002MF If identifier-10 is a class-name, a reference to the factory object of the class identified by identifier-10 is placed into each data item referenced by identifier-9 in the order specified.
  3. ISO2002MF If identifier-9 is of type String, and identifier-10 is of any type, and no implicit conversion exists between the type of identifier-10 and String, then the ToString method is applied to identifier-10 to convert it to a string, and the result is placed in identifier-9.

General Rules for Formats 10 and 11

  1. MF If more than one event-pointer-1 is specified, the results are the same as if a separate SET statement had been written for each event-pointer-1 in the same order as specified in the SET statement.

General Rules for Format 10 (Value of Event-pointer)

  1. MF The execution of the SET statement sets the value of the event referenced by event-pointer-1 to TRUE or FALSE.
    Note: When an event is set to FALSE, the execution of any thread which executes a WAIT statement which references that event suspends until the event is set to TRUE in another thread.

General Rules for Format 11 (Address of Event-pointer)

  1. MF Event-pointer-1 is set to reference the same event data item that event-pointer-2 references.

General Rules for Formats 12 and 13

  1. MF If more than one monitor-pointer-1 is specified, the results are the same as if a separate SET statement had been written for each monitor-pointer-1 in the same order as specified in the SET statement.

General Rules for Format 12 (Value of Monitor-pointer)

  1. MF If the NOT phrase is not specified, the value of the monitor referenced by monitor-pointer-1 is set to one of BROWSING, READING, or WRITING, thus establishing the corresponding form of lock. This specific lock type for this specific monitor must be eventually released by a SET statement either with a matching NOT phrase or a matching CONVERTING FROM phrase.

    For example, the lock established by

     SET mon-1 TO READING 

    can be cleared by

     SET mon-1 TO NOT READING
  2. MF The CONVERTING phrase is used to change the current type of lock established on a monitor. The lock type specified in the FROM phrase must be currently established by that thread and upon successful execution of the statement, that lock will have been changed, in one atomic operation, to the lock type specified in the TO phrase.
  3. MF Nested locks can be obtained by the execution of successive SET monitor statements with no intervening SET statement that releases the lock. Once a READING lock is established, no BROWSING or WRITING lock is allowed to nest within that thread. Once a BROWSING lock or a WRITING lock is established, any other level of lock is allowed to nest within that thread.

General Rules for Format 13 (Address of Monitor-pointer)

  1. MF Monitor-pointer-1 is set to reference the same monitor data item that monitor-pointer-2 references.

General Rules for Formats 14 and 15

  1. MF If more than one mutex-pointer-1 is specified, the results are the same as if a separate SET statement had been written for each mutex-pointer-1 in the same order as specified in the SET statement.

General Rules for Format 14 (Value of Mutex-pointer)

  1. MF The execution of the SET statement sets the value of the mutex referenced by mutex-pointer-1 to ON or OFF.
  2. MF When a mutex is set to ON, the execution of any thread that attempts to set that mutex to ON suspends until the mutex is set to OFF in the thread that set it ON.

General Rules for Format 15 (Address of Mutex-pointer)

  1. MF Mutex-pointer-1 is set to reference the same mutex data item that mutex-pointer-2 references.

General Rules for Formats 16 and 17

  1. MF If more than one semaphore-pointer-1 is specified, the results are the same as if a separate SET statement had been written for each semaphore-pointer-1 in the same order as specified in the SET statement.

General Rules for Format 16 (Value of Semaphore-pointer)

  1. MF The contents of the semaphore data item referenced by semaphore-pointer-1 are incremented (UP BY) or decremented (DOWN BY) by a value that corresponds to the value of integer-4 or the data item referenced by identifier-11; thereafter, the process is repeated for each recurrence of semaphore-pointer-1. For each repetition, the value of the data item referenced by identifier-11 is used as it was at the beginning of the execution of the statement.
  2. MF If a semaphore is set DOWN BY n and the semaphore is less than n, the thread is suspended until another thread raises the semaphore to above n.

General Rules for Format 17 (Address of Semaphore-pointer)

  1. MF Semaphore-pointer-1 is set to reference the same semaphore data item that semaphore-pointer-2 references.

General Rules for Format 18 (Size-of-Array)

  1. NETJVM The SET statement sets the size of the .NET array described by identifier-12 to the contents of the data item referenced by identifier-13 or the value of integer-5.

General Rules for Format 19 (Content-of-Array)

  1. NETJVM The SET statement creates an a .NET array of the size required to contain the values specified by the repetitions of literal-2 and initializes the array to the specified values.

General Rules for Format 20 (CONDITION-VALUE setting)

  1. NETJVM The data-item referenced by identifier-16 is set to the value of the data item referenced by identifier-17 or to condition-name-3, a conditional expression or to TRUE or FALSE.

General Rules for Format 21 (.NET-data-setting)

  1. NETJVM If identifier-18 and identifier-19 are alphanumeric or national, the ToString method is automatically invoked on the sending item and the resulting string moved to the data item referenced by identifier-18 and identifier-19. Note that the ToString method exists for any class since it is implemented in System.Object.
  2. NETJVM The sending item is moved to the receiving item.
ENTMF 

General Rules for Format 22 (Dynamic Length)

  1. The length of identifier-21 is set to zero if identifier-22 is less than zero.
  2. If the current length of identifier-21 is greater than the value of identifier-22 or integer-6, then the length of identifier-21 is set to the specified value and the item truncated on the right.
  3. If the current length of identifier-21 is shorter than identifier-22 or integer-6, then the length of identifier-21 is set to the specified value, no padding occurs, and the newly available character positions on the right are not initialized.
