Hi,

I want to copy file1 into file3 with below requirement.
Requirement: Overlay a column in file1 (position 44, length 6) with file2's field (position 31, length 6) creating outfile file fille3 for all my input records in file1. All are FB records/files as below
File1 - record length 1000
File2 - record length 200
File3 - record length 1000.
File2 will always have only a single record.
File1 can have any number of records.


I have seen examples of overlaying a field with the constant. But here I am looking for overlaying a field with the another file's field value.

Most efficient way to do it is two steps. First step process the single-record file and generate a symbol/SYMNAMES for the value.

Second step is to use the symbol to OVERLAY your value, which is by now a constant in your symbols.

Search this forum for SYMNAMES and you should find examples, often with dates.
