$IF Statement

A $IF statement provides the means whereby selected parts of the source text are not included in the compilation.

General Formats for Format 1


General Formats for Format 2


General Formats for Format 3


Syntax Rules

  1. Constant-name-1 is defined by a level 78 entry or a CONSTANT Compiler directive.
  2. If literal-1 is numeric, it must be zero or a positive integer.
  3. Directive-setting is specified in the same format as it is given in a $SET statement and may be preceded by NO. However, the format used in the $IF statement differs from the format used in the $SET statement as follows:
    1. No spaces are permitted between the NO and directive name
    2. Hyphens in the directive must be specified exactly
    3. If the directive has a parameter it may be omitted
  4. Only directives used in the syntax-check phase and produced in the directive settings list (see compiler directive SETTINGS) may be specified for directive-setting
  5. The whole statement must appear on a single line.
  6. $IF can be nested within another $IF.

General Rules

  1. Constant-name-2 is DEFINED if it is the subject of a level 78 entry or a CONSTANT Compiler directive, otherwise it is NOT DEFINED.
  2. Directive-setting SET evaluates true if the given setting matches the actual directive setting. If a parameter is specified then it must also match.
  3. The comparison between Directive-setting and the actual directive setting is not case sensitive.
  4. If the condition evaluates true the source lines following the $IF statement are processed. If the condition evaluates false, COBOL source lines are ignored until the next Micro Focus conditional compilation line is encountered.
