Emmett - constants are a good way to make code more readable

If I write:

_cr = 13
dim as Str31     s
s = "this is some text" + chr$( _cr )

It is easy to see a carriage return is being added to the end of the  
string

If I'm looking at:
s = "this is some text" + chr$( 13 )

I might have to look up what an ASCII 13 is.

Another advantage is being able to change one constant to change its  
many uses.


If I have:

_programmerName$ = "Emmett"
_city$ = "Denver"


print _programmerName$ + " lives in " + _city$
print "while " + _programmerName$ + " enjoys the weather in the  
summer, " + _city$ + " is cold in the winter"

and then imagine 30 or 40 more such assignments and/or print  
statements throughout the program.

If I want a different programmer name and city the only changes are  
the the constants ( _programmerName$ and _city$ )

If those names were hard-coded ( i.e. without constants ) the  
programmer would have to visit all 30 to 40 instances and change them.  
Not only time-consuming but potentially error-prone.
