The STx comnmand WORDS returns the number of arguments ("words" in a broader, or more technical, meaning) supplied to the command.

var := WORDS arg1 arg2argn

Note the difference between what is called a word in everyday-use, and what is called a word (an argument) here: Generally, if you supply n arguments to the WORDS command, it will return the number n, even if one of the arguments should consist of more than one "word" of natural language.

#v1 := WORDS don`'t come easy       // #v1 will be set to 3
#v2 := WORDS 'don`'t come' easy     // #v2 will be set to 2
#v3 := WORDS 'don`'t' 'come easy'   // #v3 will be set to 2, too
#v4 := WORDS 'don`'t come easy'     // #v4 will be set to 1
