Loads a program file from the specified device and merges
it
with a

d
MERGE retains the program in memory and then loads the specifle
program.
VE
The program file to be merged must have ASCII format (see the SA
command).
Note:
When a program
in
intermediate format is loaded,
an
abnormal
condition may occur.
If the line numbers overlap, the lines of the specified file replace the
lines of the program in memory.

If the device name is omitted, the device name used
In
the last file
command is assumed. For example, if the last file command is
FILES"E:",
RAM
disk E is assumed
as
the device name.
An
error occurs if the program overflows the program area as a result
of a MERGE command. Clear unnecessary variables, then try MERGE
again.
