Loop

Description

Executes the steps between a Loop.Do step and a Loop.End_Loop step, until a Loop.Exit_Loop step is encountered.

Example

This example illustrates a Loop.Do construct.

Type	Action	Recognition
Variable	Set_Value	&Var =0
Loop	Do
Log	Message	The variable is &Var
Conditional	If_Then	&Var>3
Loop	Exit_Loop
Conditional	End-If
Loop	End_Loop

Description

Terminates a Loop.Do or Loop.While construct.

Description

Exits a Loop.Do, Loop.For, or Loop.While construct. Execution continues with the step after the End_Loop step. Typically, a Loop.Exit_Loop step is placed within a conditional construct.

Syntax

&variable=begin_value to end_value;

Description

Executes the steps between a Loop.For step and a Loop.Next step until the expression in the Recognition field evaluates to False, at which point the execution skips to the step immediately after the Loop.Next step.

Parameters

Field or Control	Definition
&variable	The variable to be used in the comparison. This variable is incremented in the Loop.Next step.
`begin_value`	The starting value.
`end_value`	The ending value.

Description

Terminates a Loop.For construct. Loop.Next increments the variable in the Loop.For step.

Example

This example illustrates using the Loop.For with Loop.Next to terminate the loop.

Type	Action	Recognition
Variable	Set_Value	&Var =0
Loop	For	&Var =1 to 5
Log	Message	The variable is &Var
Loop	Next

Description

Executes the steps between a Loop.While step and a Loop.End_Loop while the expression in the Recognition field evaluates to True.

When the expression evaluates to false, execution skips to the step after the Loop.End_Loop step.

Example

This example illustrates a Loop.While construct.

Type	Action	Recognition
Variable	Set_Value	&Var =0
Loop	While	&Var <=3
Log	Message	The variable is &Var
Variable	Set_Value	&Var = add[&Var\|1]
Loop	End_Loop
