Logical Record Length

MSS works with logical record lengths as defined in the following table:

Record Format Logical Record Length
Fixed Actual record length
Variable Actual record length + 4
LSEQ Maximum record length

Note: If you have a program compiled to use EBCDIC, but that program reads a file with a RECFM of LSEQ, LRECL of 0 and a character set of ASCII, MSS automatically converts the file's data to EBCDIC as part of the read. This automatic conversion is useful when reading files such as control cards, that do not contain hexadecimal data.
