Syntax:
ERL
Description:
ERL
returns the current statement location of the program where a run-time error
occurred most recently.
• The
ERL
function works only with line numbers and not with labels.
• 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
ERL
function in error-
handling routines.
• If converted from decimals to hexadecimals with the
HEX$
function, addresses
which the
ERL
returns correspond to ones that are outputted to the left end of the
address-source list in hexadecimal (which may be printed out if a +L option is
specified in compilation).
• Since the
ERL
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.
