Description
The PROCLINE() function returns the number of the current line being executed. This function is particularly useful in conjunction with the ON ERROR command. If the currently executing line is within a procedure or function within a multi-procedure/function program or library, the line number returned is relative to the program or library as a whole. If the optional <expN> evaluates to 1, the line number returned is relative to the individual procedure or function. In this case, the PROCEDURE or FUNCTION declaration is treated as line 0 and the first executable line as line 1.
Example
m_procline = procline() message "The last line number is &m_procline. Press any key."
