<PARSE SOURCE returns 3 tokens with the following information:
1. 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 || ">."
