Re: Processing ELEM List in RPG

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!
