$TR[ANSLATE] ( expr₁ , expr₂ , expr₃ )

See 2.3 for the definition of expr.

Let s be the value of expr₁, $TR(expr₁,expr₂,expr₃) returns an edited form of s in which all characters in s which are found in expr₂ are replaced by the positionally corresponding character in expr₃. If a character in s appears more than once in expr₂ the first (leftmost) occurrence is used to positionally locate the translation.

Translation is performed once for each character in s. Characters which are in s that are not in expr₂ remain unchanged. Characters in expr₂ which have no corresponding character in expr₃ are deleted from s (this is the case when expr₃ is shorter than expr₂).

Note: If the value of expr₂ is the empty string, no translation is performed and s is returned unchanged.
