CĆ2
Within a BASIC program you may want to:
D change a counter's preset
D use the Current element of a counter for data display, logic sequencing, or other purposes
D monitor the status of a counter
To change the preset value by using a BASIC statement
D Enter a statement in this format:
name!(1)=new_preset_value
where NAME! is the name of the counter variable
The value of 1 is the location of the element CPreset within a Counter data type.
Example:
COUNTER1!(1)=50
This statement is setting the preset value for the global variable COUNTER1 to 50.
To specify the Current element of a counter in a BASIC statement
D Enter the variable in this format:
NAME!(0)
where NAME is the name of the counter variable
The value of 0 is the location of the element Current within a Counter data type.
