Keyword considerations for display files used in the System/36 environment

Some keywords in a display file containing USRDSPMGT cannot be specified.

• ALTNAME (Alternative Record Name) keyword
  Use this record-level keyword to specify an alternative name for a record.
• CHANGE record-level keyword
  Use this record-level keyword to indicate that, on an input operation, the record is to be returned to the application program only if the user has changed it.
• HELP and HLPRTN keyword
  In a file with the USRDSPMGT keyword, the HELP keyword alone will not return control to the application program. HLPRTN must be specified to return control to the application program.
• MSGID keyword
  This topic describes MSGID keyword.
• PRINT(*PGM) keyword
  How the PRINT key is handled for a display file with the PRINT(*PGM) and USRDSPMGT keywords specified is determined by how the program that is reading data from the display file is compiled and coded.
• RETKEY (Retain Function Keys) and RETCMDKEY (Retain Command Keys) keywords
  Use these record-level keywords to indicate that function keys, command function (CFnn) keys, or command attention (CAnn) keys, which were enabled on a display, should be retained when the record you are defining is displayed.
• USRDSPMGT (User Display Management) keyword
  Use this file-level keyword to indicate that this display file should be processed with System/36 environment functions.
