Defining Loops

Use the F Key Menu System to define a sequence of frames and their dwell rates as a loop, as shown in the example below. Then use a function key to invoke the loop. Use command DR to set the dwell rates; use command LS or LB to define the loop bounds. Have available an F Key Menu containing the internal instruction *Snn for one of the keys. This saves the state of the workstation under the label nn . You can do this for up to 99 loops, although there are only 48 possible combinations of F Keys. To quickly recall the loop, define an F Key with the internal command *Rnn . The only restriction is *R or *S must be the first command on a line.
