Comparing number strings and more

[nvtjellis]

I need to read the {file.idcode)that is a number string.
Read NEXT (file.idcode}.
Make both numeric.
Subtact the 1st. {file.idcode} fromt the NEXT file.idcode).
My array are field1 - field10
Use the differance as the counter and as an increment in a loop.
Here is my suedo code for the loop:
Do;
If counter < 11
Local NumberVar I:= counter;
While I <= counter
{temp_file} = ({file.idcode}} + 1)
myarray (I) := {temp_field}
Exit While;
I := I - 1;
Else counter = 10;
Enddo;
The assigned parent IDCODES are scattered. I want to show upto 10 unassigned IDCODES in the report so the can be assigned. The application "ProCare" reports do not have a report showing unassigned IDCODES......
