While Instructions Instructions Wend

Overview

Execute a block of instructions while a condition is true, unless no condition is placed after While, in which case and infinite loop will be created.

Example

MyVar = 1
While MyVar <= 10
  Print Dec MyVar, " "
  MyVar = MyVar + 1
Wend

or

While PORTA.0 = 1 : Wend ' Wait for a change on the Port

or

MyVar = 1
Do
  Print at 1,1, Dec MyVar, " "
  MyVar = MyVar + 1
Loop

Notes.

While-Wend, repeatedly executes Instructions While Condition is true. When the Condition is no longer true, execution continues at the statement following the Wend. Condition may be any comparison expression. If not condition is placed after While, an infinite loop will be created. A no condition While-Wend is only valid when both are on a separate line.
