First, you have to remove internal blanks using the -subinstr()- function

replace Variable1 = subinstr(Variable1," ","",.)

Then, you can generate the new variables exploiting the -substr()- function

gen newvar1 = substr(Variable1, 1,1)
gen newvar2 = substr(Variable1, 2,1)
gen newvar3 = substr(Variable1, 3,1)
