9.1.4 Loop Statement(while,endw) and Break Statement 

In loop statements, execution of a group of statements is repeated while the expression is true. The 
following shows the format to be used. 
 

 
• 

If the expression is t rue, the group of statements is repeated. If false, the loop is exited (and the 
statement following the endw statement is executed). 

• 

You can nest while statements up to 32 levels. 

• 

Use the break statement to forcibly exit a while loop. If while statements are nested, break exits 
from the inner most loop. 

 

9.1.5 Comment statements 

You can include comments in a script file. Use the following format. 
 

 
• 

Write the statement after a semicolon (;). You can include only spaces and tabs in front of the 
semicolon 

• 

Lines with comment statements are ignored when the script file is executed.
