RE: Question about service programs

I don't like it.

Consider SRVPGM1, made of MOD1 & MOD2

PGM1 made of MOD3 & MOD4, that will need to call procedures from SRVPGM1 (MOD1).

If you MODDIR contains
MOD1, MOD2, MOD3, MOD4

And your SRVPGMDIR contains
SRVPGM1

When you create PGM1, if you happen to specify BNDDIR(SRVPGMDIR:MODDIR), then PGM1 will end up with
MOD1 bound by copy instead of by reference.


Having specific *BNDDIR for a PGM/SRVPGM containing just the modules for that PGM/SRVPGM as Barbara
suggests isn't a really maintenance issue. The only time you'd need to maintain it would be if you
decided to add another module to the PGM/SRVPGM. Which doesn't happen often for PGM, slightly more
often for SRVPGM, but still not a big deal.

How about this?

For each unique application, create one binding directory for all
*MODULEs that ever need to be "bound by copy" (call it MODULES) and one
binding directory listing all *SRVPGMs (call it SRVPGMs).

Then, refer to either the MODULES or SRVPGMS, or both, as needed, either
in the H-spec via the BNDDIR parameter, for ILE RPG IV, or via the
CRTxxx command, or using the technique of "embedded" commands in the
source, such as with Alan Campin's COMPILE command, for all other ILE
languages.

Creating many separate binding directories, one for each *PGM or
*SRVPGM, only creates additional objects (of type *BNDDIR) that also
need to be maintained.

That's my opinion. What do you think?
