for Statement Numeric Iteration

Action

Uses numeric iteration to control the number of times a statement executes.

Syntax

for loop-var = start-expr to end-expr [step step-expr] statement

Variable	Description
`loop-var`	A loop variable to hold the current value of the for loop.
`start-expr`	A number which specifies the starting value of `loop-var`.
`end-expr`	A number which specifies the end value of `loop-var`.
`step-expr`	Optional for incrementing `loop-var` by a value other than 1. Specify a positive number to increment, a negative number to decrement. Note: You must specify an explicit `step-expr` to decrement a loop. For example, to decrement a loop by 1, specify step -1. If you fail to do this, the for statement skips the loop but does not generate an error.
`statement`	Code to be executed a specified number of times until `loop-var` is outside the range `start-expr` to `end-expr`; either a single statement or a series of statements.

Note

If you set the Step value in a "for" loop as a real, Silk Test Classic will use reals as the increments if the loop control counter is also declared as a real.

Example

[-] testcase ForExample()
	[ ] INTEGER i = 0
	[-] for i = 2 to 9 step 2
		[ ] Print(i)
	[ ] // This script prints:
	[ ] // 2
	[ ] // 4
	[ ] // 6
	[ ] // 8
