just curious now. I used to have (stil have) a licenced Lattice/SAS-C package (bought 5.0... upgraded to 6.5)
Is this abandon-ware now ? Or in other words... can I give copies away ?
"Abandonware" is not a legal definition of anything (will, copyrights expire, but anything created after Mickey Mouse seems likely to remain under copyright in the short term at least).
You are of course /able/ to give copies away. Copying software is very easy to do

The question is most likely to be one of conscience (how dearly do you love the law?)... and possibly, though unlikely, whether SAS will come after you (they still sell compilers, though not for Amiga)..
