leng,
Probably, these messages are being generated from inside a command file, or script. It is difficult to determine the true problem without knowing the commands in the command file. Try entering the OpenVMS command "SET VERIFY" before executing this command file again. That should list the commands in the file as they are executed, and you can then see the exact command that generated each error message. When that is done, enter "SET NOVERIFY" to return to normal.
You can also enter the command "HELP/MESSAGE" to see documentation on error messages.
As for what the individual messages mean:
"DCL-I-SUPERSEDE" means that a logical name was redefined. This is only an informational message ("-I-") and is not an error.
"DIRECT-W-NOFILES" means a DIRECTORY command did not find any files that matched the name entered.
"DCL-W-INSFPRM" means an OpenVMS command was entered that could not be executed because it did not have all the required parameters. (Perhaps one should have been a file name found by the previous DIRECTORY command? Or perhaps you are supposed to enter a parameter when you execute the command file?)
"COB-F-RECORD_LONG" I'm not familiar with, but it looks like a COBOL run-time library message that the program is writing to a file that is defined to have a maximum record length that is too short for the write.
"RMS-W-RTB" means "Record Too Big"; the file system (RMS) is apparently repeating the COBOL error message.
"TRACE-F-TRACEBACK" means that in response to a fatal error, the system is printing some debugging information.
So, as a tentative guess, the command file first attempted to find a file that matched some general name and failed. The command file did not abort (as it should have); instead it kept running and ran some command with a blank file name. That command started a COBOL program that is supposed to write information to the file. Since the file name was not entered, the program (or the command file) created a default file ("FILE.DAT"), but this file was created with the wrong record length, so the program could not write to it. By the way the ";129" means this is the 129th copy of FILE.DAT, so perhaps this problem has happened 129 times.
As I said, that was speculation, but perhaps it will give you an idea of what to look for.
Good luck
