Displaying a CL command definition

The DSPCMD command displays the following information for your commands or for IBM-supplied commands:

• Qualified command name. The library name is the name of the library in which the command being displayed is located.
• Qualified name of the command processing program. The library name is the name of the library in which the command processing program resided when the command was created if a library name was specified on the CRTCMD or CHGCMD command. If a library name was not specified, *LIBL is displayed as the library qualifier. If the CPP is a REXX procedure, *REXX is shown.
• Qualified source file name, if the source file was a database file. The library name is the name of the library in which the source file was located when the CRTCMD command was processed. This field is blank if the source file was not a database file.

  • REXX command environment
  • REXX exit programs
• Qualified name of the validity checking program. The library name is the name of the library in which the program resided when the command was created if a library name was specified on the CRTCMD or CHGCMD command. If a library name was not specified, *LIBL is displayed as the library qualifier.

You can use the Retrieve Command Information (QCDRCMDI) API to return command attributes that were specified on the CRTCMD command when the command was created. You can also use the Retrieve Command Definition (QCDRCMDD) API to retrieve the structure of a command definition object, including parameter information, inter-parameter dependency information, and conditional prompting information.
