Test for Net >= Fixed43
Compare, Net, Fixed43
If not, Negative If Net >= Setpoint Fixed43
Relay off, 1 turn off relay 1
End if End if
Copy [To] [From] 206 [to] [from]
Purpose: copy the contents of register [from] to register [to]
Remarks: copy does not affect the condition codes.
Example: copy, Memory1, Gross
Copy the gross weight into memory register 1
Example: copy, Memory1, Time Copy the time and date to memory register 1
Example: copy, Stime, Memory1 Copy the stored time and date to stime register for printing.
For more on time and date storage see page 49.
Dec [r] 205 [r]
Purpose: subtract 1 from a register. Set condition codes Positive, Negative, and Zero to reflect
results.
Remarks: the decimal point is ignored. If Memory1 = 0.05, then Dec Memory1 = 0.04 This
instruction is useful in creating loops that must be executed a fixed number of times.
Example: the following is an example of using the Dec instruction to implement a For/Next
loop
Set, Memory1, 25 For loop count = 25
Loop1 Do
:
<Do loop stuff here>
:
Dec, Memory1 loop count = loop count - 1
If, Positive While loop count > 0
Next1 Next loop
End if End of For/Next loop
Display [r] 218 [r]
Purpose: to display the contents of a register. The registers contents continue to be displayed
until another Display command is issued or the Gross/Net key on the keyboard is pressed.
Remarks: If the Gross/Net key is re-programmed to some function other than the Gross/net
function, then the Gross/Net key will not clear the Display [ ] command.
Example:
Display, Id1 Display ID register 1 (normally used for totals)
Div [r] = [a] / [b] 203 [r] [a] [b]
Purpose: divide register [a] by register [b], put results into register [r].
