L *-5/*+5
List a range of lines beginning five lines before the current position of the record pointer and
ending five lines after the record pointer.
L10
List line 10.
L
List the line following the position of the current record pointer. (Used for stepping through
a file, line by line.)
In the first example, TEXT is used to copy SIMCAL into a work file, and the first five lines are listed on the
screen using the LIST command (1). The LIST command is then used with the asterisk--(*)--which
symbolizes the current position of the record pointer. The command calls for a range of ten lines beginning
five lines before the current record pointer position. Since the previous command left the record pointer at
line 5, when the command is executed, lines 1 through 10 are displayed (2).
When the L[IST] command is used without any parameters, the line following the current position of the
record pointer is listed. Thus, lines 11 through 13 are stepped through (3).

In the second example, LIST is used to bring the last line of the file to the screen (1). Next, the special
character "@", which has the same meaning to RISE as the asterisk (*), is used with LIST to display the
five lines preceding the current position of the record pointer--at line 38 after the last command. Thus, the
last five lines of the file are listed (2).
