Can you please give us some clarification.
Do you need to scan the data in a PF Data file to find a character string?
Or is it a PF-SRC file where you need to scan the source members to find something..
If that is the case then you can use WRKMBRPDM.
Put ’25’ in the option field by the first member and then do F13 to repeat that option for all members. A screen will appear where you can enter the string value you are looking to find.
Are you looking to find a string either in a file name or the text description of a file or member. If so, you can also use PDM for that by using F15 to get a subset list.
