Hi Stefan,

Replace seqbase(0@0) by tmark(0@0).

That one works with constants as well.

Peter,

the changes below seem to make 3 of the 6 Music/limit tests fail with " !ERROR: interpret: no matching MIL operator to 'seqbase(int, oid)'. !MAYBE YOU MEAN: ! seqbase(BAT[void,any::1], oid) : BAT[void,any::1] ! seqbase(BAT[void,any::1]) : oid ! seqbase(BAT[oid,any::1]) : oid "

What kind of solution/fix do you recommend? (1) set the seqbase only if the type is BAT, or (2) add a "fake" constant-seqbase variant to the constant module ?

Thanks!

Stefan
