Re: WDSC V7 Program Call Wizard question

[Jon Paris <jon.paris@xxxxxxxxxxxxxx>]

Probably better in RPG400 Mark because it has zero to do with the wizard - so if you want to continue the discussion let's take it there. But ...

There is no native RPG way of doing this. Variable length arrays are not supported.

The easy fix - and the one that would benefit all users of the called routine would be to use V7's RTNPARM which will automagically convert the return value to be parm 1 under the covers. This means that only a pointer gets passed and that means the length of the array is irrelevant.

If not on V7 then the answer is to change the procedure to return the active count and make the array a parm. 

Anything else means that the whole array will always be passed.

The new XMLSERVICE routines have a nice approach which actually handles your scenario and might work for you but the service will not be as efficient due to the extra layer. It basically allows you to define an array as depending on a specified count value and then only builds the XML response to contain that many instances.
