h1. $addtokcs _Added in 1.9.0_ $addtokcs(text,token,C) Adds a token to the end of text but only if it is not already in text.
//echo -ag $addtokcs(a.b.c,D,46) returns a.b.c.D
//echo -ag $addtokcs(a.b.c.d,c,46) returns a.b.c.d
The C parameter is the ascii value of the character separating the tokens. $addtok is case-sensitive, see [[$addtok]] for case-insensitive version.
