5. Instruction Set (Program-Looping) BREAK “Exit Loop” ▫B▫Breaks out of FOR/NEXT, WHILE/WEND or REPEAT/UNTIL loop SSkips over instructions between B BB BREAK and the NEXT, W WW WEND, or U UU UNTIL instruction NNo more iterations of the loop are done EExecution continues with instruction immediately following N NN NEXT, W WW WEND, or U UU UNTIL SSkipping instruction FOR/NEXT loop iterates through range V100 = 4000-4009 However, if any value is found in D4000-4009 that is negative, looping is stopped Finds maximum value in D4000-4009 Stores maximum value in D4010 D4010 (maximum value) is initialized to zero Maximum value is stored in D4010

6. Instruction Set (Program-Looping) CONTINUE “Skip to Loop End” ▫S▫Skips over instructions between C CC CONTINUE and the N NN NEXT, W WW WEND, or U UU UNTIL instruction SSimilar to B BB BREAK except that the loop is not terminated EExecution continues with the next iteration of the loop next time the code block is scanned SSkipping instruction FOR/NEXT loop iterates through range V100 = 4000-4009 However, if any value is found in D4000-4009 that is negative, looping is continued at next iteration Finds maximum value in D4000-4009 Stores maximum value in D4010 D4010 (maximum value) is initialized to zero Maximum value is stored in D4010

7. Instruction Set (Program-Looping) FOR “Index Loop” ▫D▫Designates the beginning of a loop in which instructions between FOR & N NN NEXT are executed a predefined number of times NNo limit to nesting UUnconditional TTo make conditional place in Task and use ENTASK PParameters: IIndex – memory initialized to the From value and incremented by the By Step value FFrom – memory/constant that initializes Index TTo – memory/constant that designates the last loop value BBy Step – memory/constant by which Index is incremented by for each loop iteration NEXT “Index by Step” ▫D▫Designates the end of a FOR loop ▫Y▫Yielding instruction Finds the maximum value in the range of D4000 - 4009

8. Instruction Set (Program-Looping) REPEAT “Loop Until Condition is Non-Zero” ▫D▫Designates the beginning of a loop in which instructions between REPEAT & U UU UNTIL are executed until the ending Ending Condition is non-zero NNo limit to nesting UUnconditional TTo make conditional place in Task and use ENTASK UNTIL “Repeat Until Condition is Non-Zero” ▫D▫Designates the end of a REPEAT loop PParameters: EEnding Condition – memory location that if contains a non-zero value terminates the loop ▫Y▫Yielding instruction Ladder Code

9. Instruction Set (Program-Looping) WHILE “Loop While Condition is Non-Zero” ▫D▫Designates the beginning of a loop in which instructions between WHILE & W WW WEND are executed while the Condition is non-zero SSimilar to REPEAT/UNTIL NNo limit to nesting UUnconditional TTo make conditional place in Task and use ENTASK WEND “While End” ▫D▫Designates the end of a WHILE loop ▫Y▫Yielding instruction Ladder Code
