perl language for moving the cursor

[Thomas C. Wolfe]

What is the perl command for moving the cursor one space to the left and one space to the right?
Thnx

Perl itself cannot change the selection. You'll have to use a Nisus macro language command. Here's how to move the cursor one space to the right:

Code: Select all

$location = Selection Location
$location += 1 # add one to the location
Set Selection Location $location

If you have some Perl code that needs to calculate a more complicated selection location, just use the fact that variable values transfer across embedded Perl blocks:

Code: Select all

$location = Selection Location
Begin Perl
$location = ($location * 2) + 5;
End
Set Selection Location $location

and I suppose that
$location=Selection Location
location -=1
Set Location Location $location

means move cursor one space to the left?

Why not give it a try and see what happens? If you're writing macros you'll need to get comfortable with experimenting. It won't blow up your computer, I promise There's also the macro language reference if you're looking for a list of commands/etc.

Thanks for this. Experiment is what I shall do!
