<dd>Specifying the SFLMSGRCD keyword on the subfile record format identifies

<dd>The fields MSGKEY and PGMQ are user-defined names given to the two fields

allowed for them are their names and the SFLMSGKEY and SFLPGMQ keywords, in
|

the order shown. <p>This subfile is built by a series of output operations
|

to SFLR that place messages in the subfile as subfile records. Messages are
|
||
|
|
truncated to fit single lines (76 characters or 128 characters, depending
|
||
|
|
on display size), and second-level help is available. This subfile is displayed
|

|
|
by an output operation to SFLCTLR with option indicator 01 set on.</p>
