Here's a quick sample of accessing the valid values list:
dGetMsg pr extpgm('QMHRTVM')

Please respond to
RPG programming
on the AS400 /
iSeries
All,
This is my 1st venture into the world of API programming , and I sort of
have the concept , but I am struggling on the example below.
I am trying to retrieve the message valid reply values by using API QMHRTVM
with format RTVM0400 , I have retrieved the definition from QSYSINC for the
format , but it does not include the definition of the variable length
fields at the end of the formats fixed length fields , so I have had to
'guess' at what they should be.
The API manuals do not (as far as I can see) go into that much detail about
these.
The required parameter group has its 1st parameter as the message
information output (*) , as I see it (and I may be wrong) the format fields
are placed in here , but you have to implicitly define the length of this
variable length field via the next parameter!
I have created the below code and hardcoded in a message ID and message
file
and library (for test purposes only) and when running I get the error code
CPF24B4 in QUSBND.This informs me that a serious error occurred whilst
addressing the parameter list.
But it does not tell me which parameter is in error.
Any help would be appreciated
