COBRT099 Illegal operation in SORT/MERGE module (Fatal)
A SORT or MERGE module has received a RELEASE operation outside the Input procedure, or a RETURN operation either outside the Output procedure, or before the Input procedure has terminated correctly.
COBRT100 Invalid file operation (Fatal)
You have tried a file operation which violates a general rule of COBOL in some way. The most likely cause of this error is that you have tried a rewrite on a sequential file opened I-O, or on a relative file with access mode sequential also opened I-O, without preceding it with a successful read NEXT.
COBRT102 Sequential file with non-integral number of records (Fatal)
You have either specified an incorrect record length for a sequential file, or the sequential file you are trying to access is corrupt in some way, or the file which you have specified is not a sequential file.
COBRT105 Memory allocation error (Fatal)
The run-time system is unable to allocate sufficient memory space to successfully carry out the tried operation, probably because of insufficient memory space on your system.
COBRT106 Dictionary error (Fatal)
This could be the result of a read or write error to file or disk, but it is more likely to be the result of an internal system error.
COBRT109 Invalid checksum in run-time system (Recoverable)
The internal information in the run-time system has been altered. The run-time system might have become corrupted, or you might have illegally tried to change the internal run-time system information.
COBRT116 Cannot allocate memory (Fatal)
For some reason a part of your run-time system is unable to allocate you sufficient memory to enable you to execute your code.
COBRT119 Symbol redefined (Fatal)
The run-time system has detected a symbol (for example, data item, entry point or module name) which is already defined.
