|Syntax||FOR word number number runlist
(FOR word number number runlist number)
|Explanation||FOR allows you to execute a list of Logo
commands a specified number of times. Inputs to FOR are a
control variable, a beginning value, an ending value, and
a list of Logo commands to be executed. FOR assigns the
beginning value to the variable, executes the instruction
list, increments the variable by one, checks to see if
the variable is equal to or greater than the ending
value, and then repeats the process until the value of
the variable equals or exceeds the ending value.
The variable increment step can be changed to a number other than one by listing the increment as a fifth input to FOR and enclosing FOR and all its inputs in parentheses.
|Examples||FOR "I 1 4 [PRINT :I]
(FOR "I 1 4 [PRINT :I] 2)
