Re: "base" arithmetic in REXX
You made the best, this maybe the ermetic structure.
I suppose that STRIP leading zeroes is unuseful in REXX
/*Rexx*/
alphabet="ABCDEFGHIJKLMNOPQRSTUVWXYZ"
say d2eng(input_number)
Return
d2eng: procedure expose alphabet
i = arg(1) + 0
output=""
do while i>0
output=substr(alphabet,i//26+1,1)||output
i=i%26
end
if 0 = length(output) then return "A"
else return output
If you need to run use it heavly(more than 30 times) you can also use stem
instead substr
i.e.
/*Rexx*/
alphabet="ABCDEFGHIJKLMNOPQRSTUVWXYZ"
j = 0 ; str = '' ; len = length(alphabet)
do j = 1 to len
str = str||j' alpha.'j' +1 '
end
interpret "Parse Var alphabet "str
say d2eng(1)
Return
d2eng: procedure expose alpha. len
i = arg(1) + 0
output=""
do while i>0
output=Value("alpha."i//len+1)||output
/* or j = i//len+1
output=alpha.j||output */
i=i%len
end
if 0 = length(output) then return "A"
else return output

I don't know rexx, but couldn't you just do an OC of X'F0" into the letter.
