I am encountering some problems once again with the much maligned CPASS.
When I attempt to use it on a recent VLA data set, the following spews
onto the command line:
>forrtl: severe (27): too many records in I/O statement, unit -5, file
Internal Formatted Write
Image PC Routine Line Source
CPASS.EXE 081B95CC Unknown Unknown Unknown
CPASS.EXE 081B81A4 Unknown Unknown Unknown
CPASS.EXE 08196635 Unknown Unknown Unknown

CPASS.EXE 0804B35D Unknown Unknown Unknown
Unknown 00248DEC Unknown Unknown Unknown
CPASS.EXE 0804B291 Unknown Unknown Unknown
After which the program simply stops running. The same behavior occurs
with both TST and NEW. My inputs are appended below.
