	Although the value of the LOOP COUNTER VARIABLE can be changed in the body of a for loop, avoid doing so, because this practice can lead to subtle errors.		Although the value of the LOOP COUNTER VARIABLE can be changed in the body of a for loop, avoid doing so, because this practice can lead to subtle errors.

			For example, it is impossible to tell how many times the following loop will execute, because the user may change the value of the loop counter each time the loop executes

			00010 for i = 1 to 10
			00020 print "Enter a value"
			00030 input i
			00040 next i

	The optional numeric step_value following the STEP keyword specifies by how much to increase or decrease the counter variable with each execution of the FOR LOOP. If the STEP keyword is absent and step_value isn't specified, then the default value of +1 is used. If step_value is negative, then the counter variable is decreased with each execution of the loop.

	A '''FOR LOOP''' allows you to specify that an application should repeat a statement or set of statements until a '''counter''' reaches ~~some~~ its ~~final value~~.		A '''FOR LOOP''' allows you to specify that an application should repeat a statement or set of statements until a '''counter''' reaches its final_value.

	The '''loop body''' may consist of ''zero'' or more statements. However, the use of at least one statement in the loop body is encouraged for clarity.
