%LINE or %STATEMENT
Contains the current line number.
If the current statement is not the first statement on the line,
then the line number is followed by a period and the number of the
statement with the line. For example, if %LINE = 4.3,
then the current statement is the third statement on the fourth source
line.
If the program is at the entry or exit of a block, then %LINE contains ENTRY or EXIT,
respectively.
If the line number cannot be determined (for example, a run-time
line number does not exist or the address where the program is interrupted
is not in the program), then %LINE contains an asterisk
(*).
For COBOL, %LINE does not return a relative verb
(within the line) for labels.
%LINE is equivalent to %STATEMENT.
In the disassembly view, %LINE and %STATEMENT are
not supported.
