Hey, I resemble that remark!  I've used SPECIAL files before, but not
recently.  Prior to getting things like %editc() or the edit APIs,
they were pretty good for performing inline editing by mimicking a
one-record work file but without the disk I/O.  You could EXCPT a list
of fields with edit codes or words, then READ it back into character
fields.  Quite fast, but certainly not as nice as the BIFs and APIs.

I also used SPECIAL with SUBR01 back on the 34/36 for writing my own
utilities where I needed to read OCL between a // RUN and // CEND...

>Now  SUBR22 ..........

Was that the one where you could test the state of the inquiry latch
on the 34/36?  I think I only ever used that once.

Before Hans mentioned it, it had also occurred to me that a SPECIAL
file would be one way of doing the IFS.  And it may be a decent option
for RPG III programs.  But for RPG IV, I'm not convinced it has any
real advantage over just creating service program routines.
