Scale Basic 4.2E Reference
Get id, Memory1 Open Id 25
If, Zero If the Id was not found
Error msg, 8 display error message 8
End if End if
End End of function
Gosub (function no.) 243 [nnn]
Purpose: to execute a function (subroutine) from within a function and return to the calling
function at the instruction after the Gosub instruction.
Remarks: a subroutine can be called from within a subroutine (this is called nesting). The
maximum level of nesting is 8; i.e. function1 → function6 → function7 → function2 …
maximum = 8 levels.
Example: in a bulk-weigh function the scale is zeroed, the display is set to Net mode, and relay1
is turned on.
Gosub, Zero Zero the scale
Gosub, Set net Set the display to net mode
Relay on, 1 Turn on relay 1
End End of function
Goto (function no.) 244 [nnn]
Purpose: transfer execution from one function to another.
Remarks:
Example: If, Flag4 If flag4 is on
Goto, 7 Go to function 7
End if End if
Set pt, On, 2 Turn on setpoint 2. This instruction is not
executed if Goto was executed.
If (condition) / Else / End if 241 [nnn] / 251 / 240
Purpose: to control program flow using a condition code.
Remarks: the instructions after the if statement are executed if the condition code is true, the
instructions after the Else statement are executed if the condition code is false. The Else part
of the instruction is optional. The End if statement ends the If statement.
Example: the F1 key (activates function1) is used to toggle the display between net weight and
memory1 (total). Flag1 is used to determine the current state of the display, Flag1 = True =
display total.
If, Flag1 If current mode = display total
Flag off, 1 turn off flag 1
Display Net set to display Net weight
Else Else <current mode not display net>
