If the record TYPE determined above is variable, then the record length used will be the largest of the provided files.
If the record TYPE is fixed and one or more SORTMInns are non-VSAM, then the record length of the non-VSAM data sets will be used. Any VSAM file with a record shorter than the non-VSAM record length will have those records padded with a X’00’. If there is a VSAM data set with a record whose length is longer than the non-VSAM record length, error message WER264A will be issued.
If the record TYPE is fixed and all SORTMInn data sets are VSAM, then the record length will be the largest record length of all the VSAM data sets. Each record in a VSAM file whose record length is not the largest one will have its records padded with X’00’s.
