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. ]
