LLISTing UDGs



An anonymous reader from New Milton, Hants, mentions that

Discovery's printer port has an irritating habit, namely

that of sending question marks instead of user-defined

graphics: he points out that a program by our own Ray Elder

(ZX, Apr/May 1984, p53), originally written for the old

Kempston interface works equally well with Discovery. Here

it is, again (Figure 1); it merely replaces all the user

defined graphics with appropriate letters, A to U.



[ In fact, this program works no matter what interface you

print through, or even if you want all UDGs replaced with

letters for some reason completely unrelated to printing. ]
