Converting relative files with variable-length records

You can write a program in RM/COBOL-85 to convert variable-length relative files to fixed-length binary sequential files that ACUCOBOL-GT can use. To do this:

1. Write a program that reads the desired file using a DEPENDING ON phrase in the RECORD clause of the input file's FD. The variable depend will be filled in with the record size.

2. Define the output file as follows:

Records should be fixed-length binary sequential.
Each record must begin with two bytes that are COMP-4, and those two bytes should be filled in with the value of depend.
The remainder of the record should be the actual record contents from the input file.

3. Write the output records to a new file. Use this new fixed-length binary sequential as your ACUCOBOL-GT data file.

Note that ACUCOBOL-GT binary sequential and relative files have essentially the same format.
