I have an IBM labelled tape with four files on it and I am having problems remembering how to get the files off the tape.

The tape is and IBM, ebcdic tape bearing the label A2522.

The first file is rec size 15, block size 6000 (blocking factor 400)
The second file is rec size 134, block size (blocking factor 50)
The third file is rec size 217, block size 6510 (blocking factor 30)
The fourth file is rec size 301, block size 6020 (blocking factor 20)

My problems are: the odd record size in three of the files and the blocking facotor of 400 in the first. I know I use FCOPY with a deblock function, but how do I define the input file, what size do I build the output file and what do I do about the 400 blocking factor, size MPE has a limit of 255?

thx
