Re: Output to File vs. Report

["Charlie Massoglia" <cmassoglia@xxxxxxxxxxx>]

When you condition a file on an external switch (U1-U8), reads and writes to
the file are ignored if the external switch is not on.  So you don't have to
condition the output with the external switch.

Having said this, I haven't used external switches since the System/36.  It
is far more self-documenting to pass a meaningful parm from the CL program
to the RPG program to have the RPG program conditionally open the file in
the *INZSR subroutine.  Reads and writes to the file can  be conditioned on
an IF %OPEN(FILE).
