Display a command definition

The Display Command (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 Create Command (CRTCMD) or Change Command (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.
• Source file member name, if the source file was a database source file.
• If the CPP is a REXX procedure, the following information is shown:
  • REXX procedure member name
  • Qualified REXX source file name where the REXX procedure is located
  • 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 Create Command (CRTCMD) or Change Command (CHGCMD) command. If a library name was not specified, *LIBL is displayed as the library qualifier.
• Valid modes of operation.
• Valid environments in which the command can be run.
• The positional limit for the command. *NOMAX is displayed if no positional limit exists for the command.
• Qualified name of the prompt message file. The library name is the name of the library in which the message file was located when the CRTCMD command was run. *NONE is displayed if no prompt message file exists for the command.
• Qualified name of the message file for the DEP statement. If a library name was specified for the message file when the command was created, that library name is displayed. If the library list was used when the command was created, *LIBL is displayed. *NONE is displayed if no DEP message file exists for the command.
• Qualified name of the help panel group.

You can use the Retrieve Command Information (QCDRCMDI) API to return command attributes that were specified on the Create Command (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.
