COBRT001 Insufficient buffer space (Recoverable) You have tried to open a file directly or indirectly and, although you have not exceeded your system's file limit, something
in your system is unable to allocate enough memory space for this operation.
COBRT004 Illegal file name (Recoverable) A file-name contains an illegal character. This could be any character that is not part of the permitted character set or
it could be the system-dependent delimiter, which on most systems is the space.
COBRT005 Illegal device specification (Recoverable) Devices to which your COBOL program can write are defined by the operating system. You have tried to write to a device that
is not defined by your system.
COBRT014 Too many files open simultaneously (Recoverable) You have tried to exceed the maximum number of files which you can have open at any one time. This can be a software or an
operating system constraint, but you must not violate it.
COBRT015 Too many indexed files open (Recoverable) You have tried to exceed the maximum number of indexed files which you can have open at any one time. This can be a software
or an operating system restraint, but you must not violate it.
COBRT016 Too many device files open (Recoverable) You have tried to exceed the maximum number of device files which you can have open at any one time. This can be a software
or an operating system constraint, but you must not violate it.
