(d) Decimal point position in argument
An argument is usually specified with a sign and a decimal point. If a decimal point is not
specified, the decimal point position is assumed at the position indicated Table 4.4.2.11.
Table 4.4.2.11 Decimal Point Position in Argument
Note 1: The number indicates the position of the decimal point counted from the lowest position.
2: Numbers in ( ) indicate the number of digits right to the decimal point when the setting of
parameter “pm2004 D0 = l”.
4.4.3 Variables
Three types of variables are provided: local variables, common variables and system variables.
(1) Local Variables (#1 to #33)
Local variables are used locally for each microprogram. Each time a microprogram is called
up, new local variables (#l to #33) are secured independently for that microprogram. For the
local variables, values specified using arguments are saved or the results of operation exe-
cuted in the microprogram are saved.
For those for which an argument is passed, the value is saved and those for which argument is
not passed, the contents are <empty>. When execution of a program returns from the called
up microprogram by the execution of M99, the local variables secured, for that microprogram
