PlanetPress Talk Basics

For example, consider how you might build the following expression in a text box that accepts PlanetPress
Talk code.
pos('BLACK',trimright(@(6,18,35)))
You right-click in the text box and choose Integer functions | pos. The following appears in the text box,
at the insertion point:
pos(st1,st2)
You then manually replace st1 and st2 with the arguments you want the function to use. Recall that an
argument can be a constant, a variable, or a function. You replace the first argument with the constant
value ‘BLACK’:
pos(’BLACK’,st2)
You replace the second argument by the trimright function. You highlight the second argument, right click
and choose String functions | trimright.
pos('BLACK',trimright(st2))
Finally, you insert the data selection as the argument to the trimright function. You highlight the
argument to the trimright function, right-click in the text box, choose Select data, and select the data
using the Data Selector. When you exit the Data Selector, the data selection appears as the argument for
the trimright function:
pos('BLACK',trimright(@(6,18,35)))
