According to Bill Currie:

function DecToBin( DecInput : string ) : wrkstring; [...] trunkuti.pas: In function `Dectobin': trunkuti.pas:332: prior parameter's size depends on `Decinput' make.exe: *** [trunkuti.o] Error 1

Sorry, but I cannot reproduce the bug here. Please try to isolate the bug in a short, useless test program you can post here. Thanks for your cooperation, Peter Dipl.-Phys.
