Robert,

One way might be to eliminate the alpha characters from the string and then see if its length is the same as the incoming string.

lcstring='bob'
?LEN(lcstring) # LEN(CHRTRAN(lcstring,CHRTRAN(lcstring,'0123456789',''),''))

lcstring='123'
?LEN(lcstring # LEN(CHRTRAN(lcstring,CHRTRAN(lcstring,'0123456789',''),''))

lcstring='12s2'
?LEN(lcstring) # LEN(CHRTRAN(lcstring,CHRTRAN(lcstring,'0123456789',''),''))
