COBRT208 Error in multi-user system (Fatal)
This is normally caused by an unexpected error occurring in the network or file-sharing facilities. A corrupted network message also causes this error to be returned.
COBRT211 Program not executable by Run-Time System (Fatal)
An attempt was made to run a program that is incompatible with the currently-specified run-time system. For example, system executable, shared library, and callable shared object files that have been linked using older COBOL systems could be incompatible.
COBRT213 Too many locks (Recoverable)
You have either tried to exceed the maximum number of simultaneous record locks per file you can have, or you have exhausted an operating system or network resource; for example dynamic memory.
COBRT219 Operating system shared file limit exceeded (Recoverable)
You have tried to exceed your operating system's limit on the number of shared files that you can have open simultaneously. As this figure is operating system dependent, you should consult your Release Notes for details of how many shared files your system permits to be open at any one time.
COBRT220 Attempt to execute more than one SORT or MERGE simultaneously (Fatal)
You have coded your program in such a way that it is trying to execute more than one SORT or MERGE operation at the same time. For example, you might have coded a SORT statement in the input or output procedure of another SORT statement, an operation that is specifically prohibited under the rules of ANSI COBOL.
