0 = 1:METER:IA Store the port 1 IA value to the first location in the User
region; if the value is stored as a floating-point value, it
will be converted to integer.
1 = 1:METER:VA/100 Divide the port 1 VA value by 100 and store it to the
second location in the User region; if the value is stored
as a floating-point value, it will be converted to an
integer after the division.
2,f = 2:2800h,f;6 Starting from the port 2 address 2800h, copy 6 values to
the User region, starting at the third register; treat both
the source and destination values as floating-point
values, so each copy will move two registers.
14 = 123H Store the value 123h (291) in the fifteenth register of the
User region.
15,C = 1:GLOBAL:0;40 Copy FID string into a packed character format.
55;C;DEAD_COUNTER=5 Store a 5 in the 56
th
register of the User region and treat
it as a counter with the label “DEAD_COUNTER”.
60:0 = X Store the value of Global Element X to bit 0 of the 61st
register in the User region.
60:0;;G= Y Use Logical OR to OR the value of Global bit Y with
the current value of bit 0 in the 61st User region register.
Store the result to bit 0 in the 61st User region register
and give that register the label “GLOBALS”.
122:14 = 1 Set bit 14 of the 123rd register in the User region to 1.
97:4;I;TAR_WRD = !3:52A Store the inverted value of the Port 3 relay 52A element
to bit 4 of the 98th User region register and treat it as a
16-bit signed integer with the label “TAR_WRD”.
1 += 1:METER:VB Add the Port 1 VB value to the value in the second
register of the User region and store the result in the
second register of the User region.

Assume that region D1 on port 1 contains the string “A5F0” in registers 4 and 5. A VIEW
command displays the following:
VIEW 1:D1:4 NR 2
4135h 4630h
The objective is to convert to the integer value A5F0 (42,480). Use the SET M functions
described above to convert as illustrated below:
0 = 1:D1:5,H1L # convert and store first half of low byte
0 += 1:D1:5,H1H*16 # convert, shift, and add second half of low byte
0 += 1:D1:4,H1L*256 #convert, shift, add low 4 bits of upper byte
0 += 1:D1:4,H1H*4096 #convert, shift, and add upper 4 bits
