This may be too vague for anyone to help, but any ideas would be
gratefully received.
I'm using lots of subscripted variables which I have set up with
Symbolize (Mathematica v4). I use them in long
functions in Packages created from Notebooks with the 'Auto Save
Package' facility, and the function
definitions contain comments (* ... *).
I get things working OK, then do a minor edit and find that when I load
the package (<< blah.m) into a
notebook I get messages indicating that it has got confused by the
subscripted variable, eg:
Syntax::bktwrn:
"elect(2 B\_laser-B\_elect)" represents multiplication; use
"elect[2 B\_laser-B\_elect]" to represent a function.
(The first elect in this was the subscript of B\_elect) If I open the
Notebook that I used to create the Package
and run the function from there I don't get the message and the function
can be used fine. Sometimes the
solution seems to be to remove any spaces on either side of the
comments, but on other occasions I've not
found any spaces and I've resorted to deleting all my comments from the
function definition - which is a pity
since my programs are confusing enough even with the comments present!
