Just try the piece below:

include get.e
integer i,j,e25
atom c

e25=1
i=3j=2  --line1
c = 3.0e25 = 0   --line2
?i --3
?j --2
?c --0

?e25

?3.0e25

i=wait_key()

See 3.0e25 - this is the exponential form
of a number, so line2 is just the correct
logical expression and EU interpreter
doesn't confuse it and e25 variable.

This thing is the correct feature, 
it seems to be. But too imressive on the
first look.

The very good and clever interpreter, no?
