Basically, you can use chrtran(). This can be done in several ways; for instance:
? len(chrtran(alltrim(MyField), "abcdefghijklmnopqrstuvwxyz", "") # len(alltrim(MyField)
That is, all letters (only lowercase, in my example) are wiped out; if the length varies, then there were letters.
Difference in opinions hath cost many millions of lives: for instance, whether flesh be bread, or bread be flesh; whether whistling be a vice or a virtue; whether it be better to kiss a post, or throw it into the fire... (from Gulliver's Travels)
