Subject: Fixed a bug reported by thefox: The .CHARMAP command must not accept indices
X-Git-Tag: V2.14~247
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=e6b52ee8d07a80b03e1843f2be3d4d6b7e5d90d7;p=cc65

Fixed a bug reported by thefox: The .CHARMAP command must not accept indices
or character codes with a value of zero. The assembler runs into a CHECK in
tgttrans anyway if the index is zero.
