Writing Numerical Value on Screen

Are you displaying any variable after 'set gxout stat'? doing this will
give you a "result" for "sublin"...

Then if you use
rec11 = sublin(result,11) --> extracts record 11 from "result"... does
this contain the information you want?

and if you change
word = subwrd(result,2)
word = subwrd(rec11,2) --> extracts word 2 from record 11 from
"result"... note, we use the "rec11" from the "sublin" extraction...
does this contain the information you want?

I hope this helps,
