No, this has nothing to do with Execscript.
The execscript returns .T., but the messagebox will transform the expression to character.
For instance the following statements do work fine (tested in VFP8)

MESSAGEBOX(.T.)
MESSAGEBOX(DATE())

If I change the call of the messagebox I get this:

MESSAGEBOX(vartype(cres)) &&L
MESSAGEBOX(ALLTRIM(cres)) &&Error is fired

hth,
