Re: RPG IV and CF-spec "keep it IBM"

I believe what he is talking about is an interface to the OS/400 command
interface/prompter that would allow us to pass the variable in for return
vals. Currently this is not possible with QCMDEXC but I personally would
think this would be a handy addition. I really hate the System Domain User
Domain problem... (That being a User Domain object can not execute a System
Domain object). In the bad old days of early V2 of OS/400 I had to execute
several of the commands within the RPG function or had to crack the
parameter format for validity checking programs....

Bad example following since I know I can use the message handling APIs to
achieve the same effect.
D MSGTXT         S        300    VARY
D ERRMSG        S             7
CF  ERRMSG = EXCCMD( RTVMSG MSGID('CPF9999') MSG(MSGTXT))

Thinking about it I added theEXCCMD function This would be an IBM supplied
BIF that would hook into the OS/400 command prompter at edit time and the
command processing interface at run time. The ERRMSG return val is just a
nice to have.

Again the support for variable parameter types (which we can get the type of
by operational descriptors) and number would help us techie tool writers who
are forced by their clients to write all their tools in RPG because the
management does not want to buy another compiler... (I honestly would prefer
to write the bulk of my tool things in C++, but for Reporting, and OLTP
types of applications it is hard to beat RPG)

What do you think?
Eric
