Examples
Example 1 — Splitting apart a Sentence:
In this example:
line = "This is the very first sentence in a paragraph"
line ? (firstWord := tab(many(&letters)) (theRest = tab(0))
will capture the first word of the sentence in one variable and the rest of the sentence in a second. The result of the above expression is:
firstWord := "This"
theRest := " is the very first sentence in a paragraph"
