Message List
Effect. The READ statement is unsuccessful with I-O status code “91.”
Recovery. For a Guardian file, either remove the LOCK or open the file for I-O. For an
OSS file, remove the LOCK.
188
Cause. An attempt to position the file for a READ statement failed with Guardian error
nnn.
Effect. The READ statement is unsuccessful with I-O status code “30.”
Recovery. Type ERROR nnn to see the meaning of the Guardian error; it might
indicate corrective action.
189
Cause. The program attempted to execute a sequential READ statement when the
last operation was not a successful READ, OPEN, or START. One common cause is
attempting to do a READ after an at-end condition occurs.
Effect. The READ statement is unsuccessful with I-O status code “46.”
Recovery. Correct the program.
190
Cause. The program attempted to execute a READ statement, but the open mode for
the file is not INPUT or I-O.
Effect. The READ statement is unsuccessful with I-O status code “47.”
Recovery. Correct the program.
191
Cause. An attempt to do a tape reel swap failed. If the failure was due to a system
error, nnn is the Guardian error code. If the failure was due to the operator responding
incorrectly to the swap requests, nnn is 0.
Effect. The READ statement is unsuccessful with I-O status code “30.”
READ positioning failed with error nnn
Sequential READ requested when current position is undefined
Wrong open mode for READ
Reel swap failed with error nnn
