ERLIN

Syntax ERLIN
Location QL ROM (post JM version)

This function returns the line where the last error occurred. If the error occurred in a line typed into the command window (#0), then zero is returned (zero is also returned if there is no error).

Example

It takes a lot of time to debug programs, so save typing by including a variation of the following line in your BOOT program. Then, if an error occurs and the program stops with an error message, simply press <ALT><E> to see and edit the line where something went wrong:

ALTKEY "e","ED ERLIN-20"&CODE(216)&CODE(216),""

or:

ALTKEY "e","AUTO ERLIN",""

CROSS-REFERENCE

ERNUM returns the error number, REPORT invokes an error message and WHEN ERRor allows error trapping. ERLIN% is exactly the same.
