PARSE SOURCE

PARSE SOURCE returns 3 tokens with the following information:

• token: Operating system
  This can be OS/2, TSO, CMS or any other operating system with a REXX interpreter. (see Writing OS independent programs for an example for using this value)
  2. token: call type
  This is COMMAND if the REXX program was called from the command line, or SUBROUTINE if the REXX program was called from another REXX program. (see Parameter for a REXX program for an example for using this value)
  3. token: fully qualified name of the source file
  Note for OS/2 REXX: If this token only contains the name of the REXX program without the path, the REXX program is in the macro space.

  Example REXX program:

   /* sample for using PARSE SOURCE                                      */
  
    parse source operatingSystem commandType sourceFileName
  
    say "The Operating system is <" || operatingSystem || ">."
    say "The call type is <" || commandType || ">."
    say "The name of the source file is <" || sourceFileName || ">."
