Upper/Lower variables



Hallo
I observed the following behaviour:
variable names in Maxima are case sensitive viz. IS(A = a) ..... gives FALSE
with the following exceptions:

IS(dd = DD) gives TRUE
IS(qq = QQ) gives TRUE
whereas the other variables AA = aa etc. gives FALSE. I have reported it as
a BUG(?).
I also wanted to ask the question in the forum. Hence this mail.

Thanking you
Vijayendra
