The following limits affect file handling:
File Handling - COBOL Compiler Limits
File Handling - Run-time Limitsrun-time limits
Sequential and Relative File Size Limits
File Handling - Operating System Limits
The limits associated with the COBOL Compiler cannot be exceeded. However, at run time, the operating system or hardware can affect the operation of the COBOL run-time, thereby imposing limits that are lower than those of the Compiler. In addition, the particular configuration of the operating system or hardware environment can directly impose limits that are lower than those of both the Compiler and the run-time.
