2E Commands, YA to YDOCMSGREF › YADDDSNFM (Add Design File Member) › Parameters › Notes

Notes

1. The YADDHLPTBL command is subject to a number of size considerations:
   • Not more than 10 format names in each embedded YDFNPNLDSN or YDFNSCRDSN command.
   • Not more than 30 YDFNxxxDSN commands.
   • Not more than 100 record formats in each DDS source file member.
2. Additionally, further considerations when using the YADDHLPTBL command are: The YADDHLPTBL command makes a compilation of the DDS source. It is possible for a DDS compilation to fail. The most common causes of failure are either an incorrect library list (that is, the source can refer to a field reference file not in the library list), or that the source member is not a display file. If the compilation fails, the compilation listing is left on an output queue and a warning message is issued to the panel or the job log.

   In general, any keyword that can change a field location dynamically is ignored. To aid problem determination a warning message is added to the source file output where appropriate.

   • The following DDS keywords are ignored, and a warning message issued:

     – SFLDROP Subfile drop (fold or truncate subfile records)

     – SFLLIN Subfile line (used for a horizontal subfile)

     – USRDFN User defined data stream

   • The following DDS keywords are ignored, and a warning message is not issued:

     – ALWROL Allow roll

     – CLRL Clear line (erase lines)

     – DSPMOD Display mode

     – DSPSIZ Display size - always assumed to be 24 x 80

     – SLNO Starting line number

   • Warning messages are also be inserted for:

     – Formats not containing fields

     – Message subfile record formats.

     – Message subfile control record formats.
