Re:Problem with array sorting

Hi David,

If you are not really concern about the i/o consume, I would suggest you to idenfy pf & lf to fulfile your pgm design.
As you need to lookup the array by different key and need to be sorted.

1. create the pf, and lf1/2/3 for your criteria1/2/3;
2. you can design one pf, when you initial you pgm, you load the file into 3array by category as you mentioned.

Just for your reference. Or may you have better ideas.

Regards,
Hilda Yu

Subject: Problem with array sorting


A program loops through a DS array with 200 elements and writes out the contents. The array is never completely filled.

The subfields are roughly so :

Id
Category
Line number
Text

So, for each id, there are n lines of text to write out.

Now the contents of the array must be written out respecting a particular category order :

1 category = E
2 category <> E and <> T
3 category T

Have I a better way to do this other than just repeating the loop twice and thus doing 600 array reads instead of 200 ?

Thanks.
