Service program weirdness

["James H H Lampert" <jamesl@xxxxxxxxxxx>]

Something weird I just noticed, compiling an updated port 
of ZLIB using the supplied REXX script:
It seems that the CL front-end programs for the "minizip" 
utility suite in the package call QtmhGetEnv, in the 
QZHBCGI *SRVPGM. As shipped, the REXX script expects 
QZHBCGI to be in QHTTPSRV. On V4R2 (only our V4R2 box has 
a fully functional C compilation environment), this 
*SRVPGM is in QTCP, and the QHTTPSRV library doesn't 
exist, and so the REXX script has to be altered 
accordingly.
On V4R4 and later, the *SRVPGM is in QHTTPSRV, and NOT in 
QTCP.
Yet the CL programs compiled under V4R2, and bound to the 
*SRVPGM in QTCP are somehow successfully finding it in 
QHTTPSRV. Not being all that familiar with service program 
binding, I'm not entirely sure what to make of this. On 
another, related occasion, I found that binding a program 
to the ZLIB/ZLIB *SRVPGM keeps the program from finding 
the ZLIB *SRVPGM anywhere else, even if it's in the 
library list; conversely, neither QTCP nor QHTTPSRV are 
normally in the library list on any of these boxes.
Can anybody tell me what's going on here? So far, this 
project has been giving me nothing but weirdness.

I've also posted this query to the BBS of "UZAEMON," the 
fellow who was good enough to port ZLIB to OS/400.
