Not really. A #define is a constant, not a variable. If I recall correctly,
#define statements are technically macros and can be used to replace code
in-line.
Lingo has something akin to enumerated types in its use of symbols. They
can sometimes be used in place of a #define, like this:
(Untested off the top of my head)
on startMovie
if checkVersion() = #old then
alert "You need a later version of Director for this example"
end if
end
on checkVersion
if integer(char 1 of the productVersion) > 7 then
return #okay
else
return #old
end if
end checkVersion
Not that you don't manually "define" the symbols #old and #okay. You just
use them like constants and director handles the housekeeping.
