Syntax


WHILE log_exp 
      [VARY dobj FROM dobj1 NEXT dobj2 [RANGE range] 

      [VARY ...]]. 
  [statement_block] 
ENDWHILE.

Effect

Executes the statement block statement_block in a loop as long as the logical expression log_exp is true.

Addition

  • VARY dobj FROM dobj1 NEXT dobj2 [RANGE range]
    Obsolete: In each loop pass of a variable, assigns a value from the sequence defined in the memory using dobj1 and dobj2 to a variable dobj. The data object range limits the addressable memory area.
