dear list

on-topic for mpe folks migrating to hp-ux. 

i was just looking at the mpe to hp-ux commands crossref at
http://invent9k.external.hp.com/~csy/cmds.cgi   and had a question ('a'
question???  yeah, right, the first of many, i'm sure).

it shows that the alpha function on mpe can be done using grep, but i can't
figure out how to go about this.  

specifically, the alpha function on mpe works on a string, but the grep
command expects a file as its input. i'm not sure how to: 1) grep for alpha
only characters (i'm thinking that something like [A-Z | a-z] is needed, but
i'm not sure of the exact syntax), and 2)get grep to look at a string and
evaluate just that string.  can anyone give some pointers?

thanks!
