`.ASCIS`

A directive that specifies the values of individual bytes in the resulting code based on a given string of characters. The last byte has the inverted (XOR) oldest bit.

Syntax:

    [<label>[:]]     .ASCIS <expr> | txtexpr { , <expr> | txtexpr }

Example:

    alpha:    .ASCIS "ABC"    ; will generate $41, $42, $C3
`beta: .ASCIS "Stop", $D` ; `generates 'S', 't', 'o', 'p', $8D`

Description:

Directive .ASCIS is used to generate a string whose end is marked by reversing the oldest bit of the character.
