hi,

Can any one please suggest me how to search a mutiple strings in single go in a record.

Ex:my records has below data(in sequential file)

hello how are you, doing good
where are you from ,I am from banglore

Rerquirement:-Need to verify whether the strings 'are' 'from' present in above records. here i need scan each record for these two strings. The string position may change for each record.

Can any one please suggest me best and simply to solve this.

I tried using substring, perform loop but the processing is not efficient, becuase i have around 15 strings to search at a time in each record.

Thanks and Regards,
Pavan Kumar.M

You might need to do seperate INSPECT TALLYING for each string record by record

or if the sole purpose of the requirement is to search for strings and copy , you could think of DFSORT unless it is a NOT must do in COBOL only.

Can you show what you have tried?

Do you just need to know the sub-strings are "there" or do you need to know where they are, as in start-position?

Are the sub-strings fixed, or "dynamic"?

Why are you concerned about efficiency, is your volume of data large?

Hello,

If your goal is to parse multiple strings (15) from a large data file, be prepared for High resource consumption.
