increment alpha numeric using loop

[Jackbyte]

plz help
not sure how to put this but
in the end what i would like is
and increment from 1 to when ever for each letter in the alphabet
this is what i have in mind
psuedo

a= 0
b=0
etc..
having trouble with the loop
loop start

if textbox1.text starts with "a" then 
a=a+1

close number= "a"a

if textbox1.text starts with "b" then 
b=b+1
close number= "b"b
etc..
loop end

.. so in the form i want each time the button is clicked the alpha number increases respectively when the name is enters
in a nut shell i want to count& print how many names entered per alphabet

This may be the same answer you've already found, but I strongly advise using an array rather than separate variable names such as a and b.
