Reply with quote

Hi,

I want to calculate position of a part of a string within a string. How I can do that?

Ex:

These are the two records. I want to search the position of character
"NMN" and "UIIO" in the below records.

110013NMN IBM MAINFRAME0010TEL 99224455660009UIIO12456789
110009NMN MAINFRAME0010TEL 99224455660009UIIO12456789

Hello,

Write a loop and parse across the field using reference modification until you find the value(s) and record the position(s). . .

Hello,

We will help you implement your code - we will not write the code for you.

Suggest you search in the forum for topics that talk about reference modification.

At the top of the page is a link to "IBM Manuals". The COBOL Language Reference completely explains reference modification.

Terminology note: terminology is critical to IT, where similarly named concepts can mean extremely different things. COBOL does not have strings. COBOL has variables. These variables can be numeric, alphanumeric, alphabetic, or even national -- but they are not strings. COBOL has STRING and UNSTRING verbs that work on alphanumeric variables but they are still not strings.
