If your example is strictly true (you have all
uppercase letters, you want to map A->1,..., Z->26),
then:

forv i=1/26 {
	replace myvar = subinstr(myvar,char(`i'+64),string(`i',%02.0f),.)
}

Hello all,

My apologies if this questions seems primitive. How
can I program so that it will encode each unique
letter into a unique number? Example:
I got hundreds of combinations of strings like:
ABC
ABB
ACA
Then, encode only gives me 1,2,3 in order. But I would
like to label letter A=01, B=02, C=01 etc, and then
have encode give me 010203, etc. How can I program
this? Thank you very much,



Tj
