Restrictions on LangX COBOL expressions

In addition to the requirement that LangX COBOL expressions be enclosed in apostrophes ('), the following restrictions apply to LangX COBOL expressions:

• The following operators are supported by z/OS® Debugger in LangX COBOL expressions:
  • IN or OF
  • Subscript / index
  • LENGTH OF
  • +, -, *, /
  • // (remainder)
  • || (concatenation)
  • ( )
• In a subscript or index list, the subscript or index expressions must be separated by a comma. A space is not sufficient for separating subscript or index expressions.
• Lower-case letters are accepted in contexts other that non-numeric literals as a substitute for (and equivalent to) upper case letters.
• z/OS Debugger does not support the use of COBOL special registers (for example, DAY, DATE, and TIME) in LangX COBOL expressions.
• All non-numeric literals must be enclosed in quotation marks ("). Apostrophes (') cannot be used.
• You cannot list or alter level-88 variables in LangX COBOL.
• Only the following subset of figurative constants are supported in z/OS Debugger LangX COBOL expressions:
  • HIGH-VALUE, HIGH-VALUES
  • LOW-VALUE, LOW-VALUES
  • QUOTE, QUOTES
  • SPACE, SPACES
  • ZERO, ZEROES, ZEROS
