Several listings are being stored using the CONLIST utility that have different record lengths and record formats.
What record format is used? Does any of the data get truncated?
CONLIST will store all members in the record length and record format of the output file (DD C1LLIBO).
If the input file is shorter, blanks will be padded at the end of the record. If the output file is shorter, the input file the data will be truncated to fit the output file's record length.
