Re: Processing ELEM List in RPG

Rich

Create a data structure. Make arrays within the data structure. Have a 2-byte integer as the first element, then there is an array of offsets to the values. Then the array of values.

The offset array will have only as many elements as the initial counter, so the array of values starts at different places. Use a pointer to an array of values. Set it to where it should start, according to the offsets - or simply have a pointer to the value, then set the pointer by the offset arrays.

For more complex lists, have several of this kind of thing in the DS. There will be offsets to the various components.

Easy-peasy!

Or even better, use REXX - it just works!

Ducking!

Hello All,

I am adapting a CL command to use an element list qualifier and pass the list to an RPG program.

I then want to process the resulting list from the RPG program.

I have done this in a CL program in the past and want to start using RPG as the CL command processing program instead.

Anyone have an example of doing this from an RPG program ?

It appears the first 2 positions have the element count, but there are some additional binary values after the count before the actual data buffer begins.

I need to determine the best way to traverse the element buffer.

Anyone have any input on this ?

Thanks in advance.
