Hi All,

Can anyone please help me with a special scenario for string searching.

I have a string like ABCDEFGHIJKLMNOPQRSTUVWXYZ and i have to search this string like when A and D are present but B is not present.
Is there any way in cobol?

Thanks Nitin

Use reference modification on the string. Pseudo code is:

Set count to zero.
Loop from 1 to length of string
If string character = 'A' or 'D'
Add 1 to count
End-if
If string character = 'B'
Subtract 1 from count
End-if
End-loop
If count = 2 do matched logic
