>I was going to modify it to point out that Andrew did NOT say that there was a difference in the way classes & .PRGs were compiled, what he speculated was the lack of compilation (tokenizing) was for some reason not allowed in classes.<

His original statment

>>I expect it is because class files are binaries, and the & command is inline, hence only works in the "interpreted" .prg files.. ie. & means "dont compile it because it will be different sometimes".. which in a file which is compiled (ie a class file) is illegal.<<

says .prgs are interpreted and classes are compiled and that & would therefore not work in a class.
