High−level Instructions
Description
The program for the file name stored in the area specified by S is read from the IC memory card, and is
substituted for the program currently being executed.
Subsequent operation is carried out based on the program which was read.
Precautions when changing programs
Programs are changed when the ED instruction is executed. At that point, the mode changes automatically
from the RUN mode to the PROG. mode.
All output goes off.
The contents of memory areas not specified as hold−type are cleared.
When a program is read, the system registers are rewritten at the same time. The same system register
settings as those of the specified program should always be used, including the I/O map, remote I/O map, and
others.
