Syntax:
ERR
Description:
ERR returns the code of a run-time error that invoked the error-handling routine.
• The returned value is in decimals, so it may be necessary to use the
HEX$ func-
tion for decimal-to-hexadecimal conversion when using the ERR function in error-
handling routines.
• If converted from decimals to hexadecimals with the
HEX$ function, codes which
the ERR returns correspond to ones that are listed in Appendix A1, "Run-time
Errors."
• Since the
ERR function returns a significant value only when a run-time error
occurs, you should use this function in error-handling routines where you can
check the error type for effective error recovery.
