For a string variable, -length(variable)- is equivalent to
-length(variable[1])-. That may or may not be a correct answer. 

Also `j' is the same as `i' here.

Andri,

Perhaps something like this ....

local len=length(variable)
local j=0
forval i=1/`len' {
    local j=`j'+1
    gen str1 var`j'=substr(variable,`i',1)
}
