dscan or lup
motor scan relative to the starting position
SYNOPSIS
dscan motor start end intervals time
lup motor start end intervals time
DESCRIPTION
dscan (also called lup) scans one motor, as specified by motor. If the motor is at position X before the scan begins, the scan will run from X+start to X+end. The step size is (start-end)/intervals. The number of data points collected will be intervals+1. Count time is given by time, which if positive, specifies seconds and if negative, specifies monitor counts.
Upon termination, the motor is returned to its starting position.
EXAMPLE
