RE: RPG enhancement suggestion

[Colin Williams <Williamsc@xxxxxxxxxxxxxxxxx>]

This is what happens if you specify DEBUG(*YES) in your programs, 
which is included so that a DUMP can be produced as part of the error
processing,
but also means that every field is read in from every file.  

This is the standard at my current company, 
and at every other place that I have worked, where they include the DUMP
opcode as part of their error processing.

Sorry, it wouldn't be any faster, since RPG already does
something like that.  If an input field is not used within
the program, the data is not moved from the input buffer
to the field.
