COBOL Error Code :

030

Reason for this Error in COBOL

File system is read-only (Recoverable) -The file system which you are using is read-only, which effectively means that it is write-protected. You have tried to change a file in some way, for example you might have tried to WRITE to a file or to DELETE information in it. -You should abandon your attempt to alter the file unless you can make your own personal copy of it. You should then be able to alter the contents of your copy, but not of the original source.
