StringTools

 Chop
 remove the last character of a string

 Calling Sequence Chop( s )

Parameters

 s - Maple string

Description

 • The Chop(s) command returns a copy of input string s with the last character removed, if the string is nonempty. As a special case, the empty string is returned unchanged.
 Note: This function is similar to the Perl function of the same name.
 • Compare this procedure with the other perl-esque routine StringTools[Chomp], which removes only line ending characters.

 > $\mathrm{Chop}\left("This is a test."\right)$
