The Record Length of the file is too big.
50
Cause . . . . . : The file has a record length greater than the limit allowed. The compilation ends. For a program-described file the record length specified in positions 23 - 27 of the File Description specification is greater than allowed. For an externally-described file, a record was found with a length greater than allowed.
Recovery . . . : Change the record length to a value between 1 and the largest allowed. Compile again.
