Loop and loop-related commands reside on the Program Editor's Control and Transfers menus. When you insert one of the loop structures, its template is inserted at the cursor location. You can then begin entering the commands that will be executed within the loop. For...EndFor loops A For...EndFor loop uses a counter to control the number of times the loop is repeated. The syntax of the For command is: Note: The ending value can be less than the beginning value, provided the increment is negative. For variable, begin, end [, increment] À Á à À Variable used as a counter Á Counter value used the first time For is executed  Exits the loop when variable exceeds this value à Added to the counter each subsequent time For is executed (If this optional value is omitted, the increment is 1.) When For is executed, the variable value is compared to the end value. If variable does not exceed end, the loop is executed; otherwise, control jumps to the command following EndFor. i { 5 i > 5 For i,0,5,1 EndFor -------- Note: The For command automatically increments the counter variable so that the function or program can exit the loop after a certain number of repetitions. At the end of the loop (EndFor), control jumps back to the For command, where the variable is incremented and compared to end. For example: Programming 697
