Actually it is possible with DASM. You need to use the SEG
pseudoopcode like
SEG.U variables ;this segment won't produce output
ORG $80
vara ds 1
varb ds 2
varc ds 5
SEG code ;this segment will get into the bin file
ORG $F000
etc.
You can use the SEG command to have different banks with the same
origin too. That is helpfull for writing bankswitched programs.

A PC version of DASM 2.12-04 exist. It can be found in the
C64 devellopment directories of ftp.funet.fi . I have posted
the exact URL the the list some time ago and can do again,
if you can't find it on your own.
Ciao, Eckhard Stolberg
