When the execution condition is OFF, FLSP(183) is not executed. When the ex-
ecution condition is ON, FLSP(183) reads the step program file specified in C+1
to C+4 (
filename
.SFC) from the Memory Card and writes the data over the step
indicated by N, changing the contents of the action block. The step program file
must be written to the Memory Card beforehand with the CVSS.
A step that is active or that contains actions that are still being executed cannot
be changed. Also, the number of actions in the new step must be the same as the
number in the step that is being overwritten.
The contents of C must be all zeros to indicate the Memory Card and the file
name is specified in C+1 to C+4 as shown in the following table. If the filename is
less than 8 characters long, enter #20 for the bytes that aren’t required. It is not
necessary to input the filename extension “.SFC.” It is assumed.
