See also the description of comparison operations, which discuss the comparison of characters.

<character>	[Instantiable Class]
<character> is a subclass of <object>.

as-uppercase[return to first citation]   character   ==>  uppercase-character	[G.F. Method]
The <character> on as-uppercase returns the upper-case equivalent for character. If character already is uppercase or does not exist in two cases, it is returned unchanged.

as-lowercase[return to first citation]   character   ==>  lowercase-character	[G.F. Method]
The <character> on as-lowercase returns the lower-case equivalent for character. If character already is lowercase or does not exist in two cases, it is returned unchanged.

as[return to first citation]   <integer> character   ==>  integer	[G.F. Method]
This method on as returns a numeric equivalent for character. The integer returned may be implementation dependent. (It may often be ASCII but could be something else where ASCII is not appropriate.)

as   <character> integer   ==>  character	[G.F. Method]
This method on as returns the character equivalent to integer. The meaning of integer may be implementation dependent. (It may often be ASCII but could be something else where ASCII is not appropriate.)
