incrementing letters like we do numbers...

I am looking for the most elegant way (i.e the fewest lines of code) to increment through the alphabet in a way similar to how i would do it with numbers.  

every year, i need to code to create the 26 folders for each letter of the alphabet.  below is the basics of the code that i would like to use (but it does not work because when you add “1” to a a variable that is a letter, the variable becomes a number instead of incrementing the letter):  

fld_ltr::':
::folder_letter="A":
fld_lop::':
::folder=root_folder{slash{company_name{slash{"photos"{slash{job_year{slash{folder_letter:
::unix="mkdir"<folder:
::system noredraw unix
:folder_letter eq “Z":return:
::folder_letter=folder_letter+"1":
::goto fld_lop:

I am hopeful that i can avoid writing 26 differently lines of code to account for each letter folder.  thank you very much,
