RE: IFS in RPG

[Joel Fritz <JFritz@xxxxxxxxxxxxxxxx>]

Seems to me that bifs to wrap the Unix Type file APIs wouldn't be a bad
thing.  It would standardize things nicely.  OTOH, the prototypes aren't
arcane.  I don't think being able to put the file name on an F spec would be
as helpful as it may sound.  One thing you lose immediately is the ability
to use string variables for file names.  I've always found that to be the
only annoying tradeoff in RPG file I/O.

Stream files are harder to deal with than database files.  There's no way
around it.  Opening, closing, reading, and writing are the easier parts.
The harder part is parsing and manipulating the data once you get your hands
on it.
