Example: goto 1000

end

1000

print "code execution continues here"

FOR / TO / NEXT This is a “For To” loop with the following form:

FOR var = start value TO end value

Command(s)

Example: for x = 1 to 10

Print x

The start value and end value must be whole numbers with the start value

less than the end value. There can be 5 nested FOR / TO / NEXT sections.

IF / THEN IF condition THEN action. Condition is a logical expression that

evaluates to true or false. If the condition is true then the

desired action is executed. Valid conditional operators are:

Operator Example

< a < b a less than b

> a > b a greater than b

<= a <= b a less than or equal to b

>= a >= b a greater than or equal to b

= = a = = b a equal to b

!= a != b a not equal to b

Example: if stage>10 then print "stage is greater than 10"

Most commands can be used after the THEN statement. A few

possibilities are listed below:

Then goto ####

Then gosub ####

Then measure(x)

Then delay(#)

END All programs should end with this statement.
