RE: Filling an array from the first occurrence on down

I'd go one line further to prevent it from trying to copy a line to itself:

x = 0; // more clear than 'Clear'
For i = 1 to %elem( Line );
If Line(i) <> *blanks;
x += 1;
If i <> x; // x can't get larger than i
Line(x) = Line(i);
Clear Line(i);
Endif;
EndIf;
EndFor;

Good change there, Alan.  My code would have laboofinated the array if there were no blank elements.

Thanks for your reply Kurt
Your example was FAR, FAR simpler than some of the concoctions that I created Embarrassment forbids me from posting some of the examples Suffice it to say that Dr Frankenstein would have been proud of some of my creations/monstrosities I just needed to make one change Here is what I am presently testing

Clear x;
For i  = 1 to %elem( Line );
   If Line(i) <> *blanks;
      X += 1;
     Line(x) = Line(i);
     If i > x;
       Clear Line(i);
      Endif;
    EndIf;
EndFor;

MUCH appreciated

I think this will do it.  Not tested.  This is assuming the non-blank data is already sorted, just that there are blank elements mixed in.

Clear x;
For i  = 1 to %elem( Line )
   If Line(i) <> *blanks;
      X += 1;
     Line(x) = Line(i);
     Clear Line(i);
   EndIf;
EndFor;

Hi everyone
I'm having one of those days where no matter what I do, I just cannot get my head around what should be a simple problem Hopefully someone is kind enough to provide an answer I have an array
D LINE            S             30    DIM(6)

Data can be in any combination of the occurrences (or none at all) I need to create logic so that data is moved down to fill in from the first, through the second, then third etc., until the only blanks are in the trailing occurrences

Hopefully I explained it correctly, here is an example
1
2    data 1
3
4
5   data here
6  f=data 2

Becomes
1 data 1
2 data here
3 f=data 2
4
5
6
NOTE - I don't want the information sorted, just moved up As always, any and all responses gratefully appreciated
