Here is a short code fragment:

''''' Start of code

defint a-z

com.port=&H3fe

print "Reading 'com.port':";inp(com.port)
print "Reading '&H3fe':";inp(&H3fe)
print "Reading 'int(com.port)':";inp(int(com.port))

system

''''' End of code

Guess what:  The first line gives incorrect results -- it's not
reading port &H3fe!  (I'm trying to read the RI pin; I know &H3fe is
not the _data_ port!)


What's going on here?  What is the difference between com.port (an
integer variable) and int(com.port)?
