IBM 5150 User Manual

Removing a Statement
To delete a line from a program, type only the line
number and then press
the Enter key.
For example, to delete the statement that we just
added to print 4, type:
12
and then press the Enter key.
Note: Remember
the discussion of the Esc Key in
the "Using DOS" chapter? Well,
don't use the Esc
key
to try to delete a program line. The Esc key
just erases the currently displayed line from
the
screen. It does not change the original line in the
program; the original line will still remain in the
program.
