When you nestFor...Nextloops, you must use different controlvariablesin each one. This error has the following cause and solution: An innerForloop uses the same counter as an enclosingForloop. Check nested loops for repetition. For example, if the outer loop usesFor Count = 1 To 25...

In this final chapter on flow control, we will look at another of the shell’s looping constructs.The for loop differs from the while and until loops in that it providesa means of processing sequences during a loop. This turns out to be very useful when programming.Accordingly, the for ...

Operation for setting the initial value of the loop control variable. This comes from the expression between the 'For' and 'To' keywords.

The linear solenoid’s position is controlled in a feedback loop. For example, a valve’s downstream pressure can be monitored and used as a feedback signal to compare with the setpoint, adjusting the pulse-width modulation (PWM) duty cycle to control the solenoid. However, it may be diffi...
