-5 CHECKSUM ERROR
Cause The edit control block was invalid. There are two possible causes:
• The program called EDITREAD before calling EDITREADINIT.
• The program modified the edit control block, which invalidated the control block.
NOTE: If you accidentally set the edit control block's reposition bit to 1, you will not receive this
error. When the reposition bit is 1, checksum validation is disabled during the call to EDITREAD.
Effect The operation terminates.
Recovery Correct the program error that caused the problem.
