If an SP-ASSIGN H command is executed from a Proc, it will leave a mark with the print file number in the secondary input buffer at the time when the ENTRY # is displayed. The mark is the ERRMSG number [1099]. If the process generates the following message:
|
HOLD ENTRY #17 |
then the PROC secondary input buffer will contain:
|
1099 17 |
It will also contain any other error message numbers which are generated during execution of the command.
In the following example, a portion of a Proc retrieves a hold file entry number for a succeeding SP-EDIT.
|
