When is a CAT not a CAT

["Chris Devous" <cdevous@xxxxxxxxxxx>]

Well, this is interesting.  What am I missing?

CPHON = '503-829-8080   '
At the ass end, sPhone = '               ', but I think it *should* = 
'5038298080     '


D PHNAR           S              1    DIM(15)
C                   Eval      sPhone = *Blanks
C                   MoveA(P)  CPHON         PHNAR
C                   Eval      X = 1
 *
C                   DoU       X = 15
C                   If        PHNAR(X) <> ' ' And
C                             PHNAR(X) <> '-' And
C                             PHNAR(X) <> '(' And
C                             PHNAR(X) <> ')'
C                   Cat       PHNAR(X)      sPhone
C                   EndIf
C                   Eval      X = X + 1
C                   EndDo

I've also tried Eval    sPhone = sPhone + PHNAR(X)

But, to no avail.  I are unable to build my phone number.

I watch in debug, and I see the cat/eval instruction execute, but no data goes 
into the
result.

Anybody know why?  Am I a dummy?

TIA,

Chris
