RE: Tail400? (was Piping and Redirection)

Zak:

Suggestions? Hmmm... Try the following ILE CL module. Compile it and then do 
CRTPGM with it, specifying BNDDIR(QSYS/QC2LE). As a bare starting point, it 
might give you some ideas for how to handle the display. Change values and see 
what happens; check other DSM APIs for other effects.

RollScn CL:

pgm

   dcl    &NbrLines        *char     4
   dcl    &TopRow          *char     4
   dcl    &BotRow          *char     4

   chgvar      %bin( &NbrLines   )   2
   chgvar      %bin( &TopRow     )   4
   chgvar      %bin( &BotRow     )  10

   callprc 'QsnRollDown'    ( +
                              &NbrLines    +
                              &TopRow      +
                              &BotRow      +
                              *omit        +
                              *omit        +
                              *omit        +
                            )

return
endpgm

Then, for a PF, consider writing a bare program with a program-described file 
of record-length, say, 32766. Before calling that program, issue an OVRDBF to 
point that file to the one you want to TAIL and specify EOFDLY(*NONE) and 
LVLCHK(*NO). Convert each record you read to include displayable-only 
characters, roll the screen down a line and display your record on the now 
available line.

Modify to taste. Investigate REUSEDLT() PFs also.
