As I explained in the beginning of this thread it somehow relates to the TOS. The same SMSQ.PRG work with emutos but not with 1.62. I guess I can patch the binary. But if this (the bad moveq ) fails there are probably more places that gets wrong. _______________________________________________ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm
