Vern,
I think perhaps the terminology is easy too confuse...
According to Fortress Rochester (p. 140)
Static procedure calls = "early binding"
Dynamic program calls = "late binding"
The resolution of an ILE procedure reference at program activation is
not considered "binding".
In any event, I did not mean to imply that the binding directory was
needed at other than compile time.

Charles, I'm a little confused with your statement - "only used for--
during the binding phase" - as you said, perhaps implicitly, there are 2
binding phases - one at program creation (early) and one at program
initiation (late).
The binding directory is not used for late binding - we never distribute
a binding directory with our products, for example, unless customers
will use one of our service programs for their development - that's the
same as IBM's QC2LE, for example. The binding directory is used for
creating a program - so that the linker can find where the various
references are located or will be located at run-time.
Although it seems Birgitta has an ugly situation, I prefer to use *LIBL
in BNDDIR entries - then I don't need to make a copy and change the
library when I bring an object into my development sandbox.
So far this has made sense for me - hope I'm not completely nuts, of
course - maybe a little but not completely!

The only benefit for them is so that you don't have to specify
individual modules on the MODULES parm or individual service programs
on the BNDSRVPGM parm of CRTPGM or CRTSRVPGM.

Hi Birgitta,
when you DSPPGM, on the *SRVPGM tab, there is both srvpgm name and
library. So yes, a PGM can bind to a qualified SRVPGM or a SRVPGM
found on the *LIBL.
some minor terminology. You compile a module. Then create a program
from those modules.
I find binding directories of little value add. I don't use them. Not
knowing much about the mechanics of them, I don't think a binding
directory comes into play after the program is created. When a program
is called and activated, it binds to the SRVPGMs listed in the
DSPPGM/SRVPGM tab.

Hi,
someone can explain the following situation.
I had to compile a CGI Program that calls procedures from a service program.
This service program is located in a different library.
The service program is also located in a binding directory that is used for
compiling the CGI program (H-Specs)
Until now everything worked great.
Yesterday the program was compiled (without problems), but as soon as it get
called from an web application I got an "Internal Serve Error".
After searching through all available logs, I found out an MCH3401 (Service
Program could not be found) was sent.
The program was recompiled last time around a week ago. A modification in a
procedure in the service program was made after.
So I also recreated the service program, recreated my program ... and still
got the same error.
The program could be called from a command line without problems, that means
the service program was found.
After a long search I found out the service program within the binding
directory was not specified with Library *LIBL.
I changed it to the library in which the service program is located.
... recreated everything ... and everything worked great.
... Is the library information stored somewhere in the caller
(service-)program so it is found and activated directly??????
Mit freundlichen Grüßen / Best regards
Birgitta Hauser
