RE: MODS Likerec

["Florin Todor - YYZ Concord" <ftodor@xxxxxxxxxxxxxxxx>]

Thanks Booth, but my problem is not sorting an array (even if I understand what you meant here); my problem is re-loading the subfile from an identical DS (actually an array of DS's; the number of array elements (DS's) is equal with the number of initial subfile records).
 


Thank you

Here is how I did this in a learning program:

D                 ds
D  Array                        40    dim(50)
D   Col1                        10    overlay(Array)
D   Col2                        10    overlay(Array: *next)
D   Col3                        10    overlay(Array: *next)
D   Col4                        10    overlay(Array: *next)

             sorta Col2;

Load the new rows that you wish to add at the end of the array, then 
when you are ready to reload the subfile sort the array by what ever 
field you wish to sort by.  Then there is no issue with inserting new 
records at the right moment.  The nice thing about this solution is that 
you can set up the sorting on whatever column you like; you are not 
locked into the loading sequence.

There's more lil tricks if you want to sort by column heading, or if you 
want to sort descending as well as ascending, but that would belabor 
this point.
