Language Features - Speed

ALTER
Allows ALTER statements in your program.
FASTCALL
Controls the behavior of a called program. If FASTCALL is specified, the program does not set up information to allow it to determine whether it is a main program. The program always assumes that it is not a main program, and EXIT PROGRAM will always cause an exit to the calling program.
FASTLINK
Tells the Compiler that the parameters in the USING clauses of the Procedure Division statement and each ENTRY statement conform to certain restrictions. This enables it to produce faster code.
FIXOPT
Changes the way in which generated code accesses the Data Division in object (.obj) code.
QUAL
Allows qualified data-names and procedure-names in your program.
QUALPROC
Allows qualified procedure-names in your program.
SEG
Turns on COBOL segmentation.
TRICKLE
Tells the Compiler that the program contains legal but unstructured perform-ranges, and that certain optimizations cannot, therefore, be made.
