String and character manipulation commands

These commands provide functionality to classify characters, convert characters between character and numeric values, convert an index into a string, determine the length of a string, extract a range of characters from a string, replicate a string a number of times, and transliterate a string (similar to the UNIX tr(1) program).

Available commands are:

cequal(1tcl)

cexpand(1tcl)

expands backslash characters in a string to actual characters

cindex(1tcl)

returns the character indexed by the given expression from string

clength(1tcl)

returns the length of a string in characters

crange(1tcl)

returns a range of characters from a string

csubstr(1tcl)

returns a substring of characters from a string

ctoken(1tcl)

parses a token out of a character string

ctype(1tcl)

tests whether characters in a string are of a given class

replicate(1tcl)

replicates a string n times

translit(1tcl)

changes characters in inrange to outrange
