^Parameter^Description^
|//Expression//|Char requires that the value of //expression// be an integer within the range 0 to 255.|

Char will be compiled as a special load instruction, if the Char expression is an integer constant. This instruction generates less object code, and is executed much faster. In the following example, Char assigns a field mark to the //field_mark// variable.\\ \\ field_mark = Char(254)
