For these two,

lcChop=strextract(lcString, "~", "^^", i)

(i =1,2, 3,...)

If the ending delimiter isn't sure to be a ^^, you can go like this:

lcDig=""
for i=1 to getwordcount(lcS, "~")
   lcWord=getwordnum(lcS, i, "~")
   j=1
   do while isdig(substr(lcWord,j))
      lcdig=lcdig+substr(lcWord,j,1))
   enddo
endfor

outer loop counts words split at tilde, inner pulls starting digits from these words until a non-digit is encountered..
