Vern,

What does this have to do with my answer to Rory?

Rory was asking if there was a need to add additional conditional compile statement in the existing code, in a response to Tom's solution, where they have two sets of objects from the same source code. I simply said no, there was no need to change any reference to record formats in the existing code.

Where did I show my naievty to how the handlers work? Where did I say anything anout a handler using the native IO? Where did I say anything about rewriting anything to use display API's? Where did I say anything about making it conditional at runtime? Where did I say anything about adding to anybody's workload?

My cage is rattled by your response. Do you get that?

Crispin

The issue comes from a desire to use the completely native solution -
from the same source code. A program using a handler simple cannot use
the native IO - it shunts everything to the handler for each op-code.

I can certainly see where, with WORKSTN or PRINTER files, that you might
want to print locally or to Excel, show a green screen or a browser -
those things are not easily conditional, if at all, at runtime. You
COULD write something using display APIs, perhaps, but this technology
is supposed to make things easier - not add to your workload.

I like Tom's solution - and, as he says, it doesn't seem to raise any
editor syntax errors.

Rory,

RPG OA uses the existing code, and just passes info to the handler as
parameters. No changes required to the rest of the source, so I can't see
why any additional conditioning would be required...

Nice solution, Tom. Do you also need to use this method anywhere else (when
specifying record format names for Write, Read etc.)?

This example that I created does NOT raise a syntax error since you use a
/COPY with the HANDLER.
FCEN106D CF E WORKSTN
/copy cenhnd

(will not raise the syntax error, because SEU does not know I am using a
handler)
Source member CENHND

/if defined(USE_HANDLER)
F Handler('ASNAWINGS')
/endif

(get the syntax error here, but you only touch this once)


We are keeping two object libraries, one for the handler RPG objects and
one NOT.
The 5250 programmers compile like they normally do, and DO NOT get the
syntax error when they go into the source.
We compile with CRTBNDRPG define(‘use_handler’)
If we accidently compile it to the wrong place, they just need to
re-compile without the parm to make it work.
