An expression of the form `tt(##)var(x)' where var(x) is any character -sequence such as `tt(a)', `tt(^A)', or `tt(\M-\C-x)' gives the ASCII -value of this character and an expression of the form `tt(#)var(foo)' -gives the ASCII value of the first character of the value of the -parameter var(foo). Note that this is different from the expression -`tt($#)var(foo)', a standard parameter substitution which gives the -length of the parameter var(foo). `tt(#\)' is accepted instead of -`tt(##)', but its use is deprecated. +sequence such as `tt(a)', `tt(^A)', or `tt(\M-\C-x)' gives the value of +this character and an expression of the form `tt(#)var(foo)' gives the +value of the first character of the contents of the parameter var(foo). +Character values are according to the character set used in the current +locale; for multibyte character handling the option tt(MULTIBYTE) must be +set.
