One more thing to try. I'm always very leery about syntax with only one
static word at the beginning. I would add one more thing:
SET VAR vCommand = ('Print' & .vReport & .vWhere_Clause & .vSort_clause &
vOption_Clause)
&vCommandKaren > PRINT .vReport &vWhere_Clause &vSort_Clause &vOption_Clause > > >
