Re: Sort a field within an array

[Rory Hewitt <rory.hewitt@xxxxxxxxx>]

Willie,

The reason you're getting a DDE is that some elements of the array (ones you
haven't populated) have blanks in the alot1 subfield.

At V5R3, you can specify %SUBARR with SORTA:

SORTA %SUBARR(alot1 : 1 : X );

assuming X is the highest element you have loaded

Alternatively, you could simply initialize the alot1 subfield with *HIVAL
prior to doing any loads:

eval alot1(*) = *HIVAL;

and then you can use a simple SORTA after all the loads:

SORTA alot1;

Either option should work.
