Basic
MERGE pathname
Loads a BASIC program and merges it with the program currently
in memory. Program lines in
pathname
are inserted into the resi-
dent program in sequential order. The file must be in ASCII for-
mat; that
is,
it must have been saved with the A option.
If
line numbers in
pathname
coincide with line numbers in the resi-
dent program,
pathname's
program lines replace the resident pro-
gram's lines.
