$GetL
The $GETL function returns the line number of the current line on the page on the user's terminal or on the output data set specified by a USE command. The first line on a page is line number 1 and is the line on which header 0 appears. The current line is the line actually being printed if $GETL is invoked:
- From a PRINT statement
- After a PRINT statement that ends with an ellipsis (...).
Otherwise, the current line is the next line to be printed. The current line becomes line 1 as soon as the bottom line of a page has been printed. $GETL takes no arguments.
