Commands can return a value in "the result."
create folder myPath
get the result
if it is not empty then
answer error it
While not pertinent in this context, commands & functions can also
return values via referenced parameters:
function validDate theDate, at theDay, at theMonth, at theYear
.... --parse theDate for validity
if itsADate then
convert theDate to dateItems
put item 1 of theDate into theYear
put item 2 of theDate into theMonth
put item 3 of theDate into theDay
on dateElements theDateItems, at theDay, at theMonth, at theYear
put item 1 of theDateItems into theYear
put item 2 of theDateItems into theMonth
put item 3 of theDateItems into theDay
In both the function and the command the values of the variables passed
in the last three parameters are updated in the calling handler.
