Processing ASCII file labels

Standard label processing for ASCII files is the same as standard label processing for EBCDIC files. The system translates ASCII code into EBCDIC before processing.

All ANS user labels are optional. ASCII files can have user header labels (UHLn) and user trailer labels (UTLn). There is no limit to the number of user labels at the beginning and the end of a file; you can write as many labels as you need. All user labels must be 80 bytes in length.

To create or verify user labels (user label exit), code a USE AFTER STANDARD LABEL procedure. You cannot use USE BEFORE STANDARD LABEL procedures.

ASCII files on tape can have:

Any labels on an ASCII tape must be in ASCII code only. Tapes that contain a combination of ASCII and EBCDIC cannot be read.
