>>>Not sure I get you there BB. However, the point is that I do not see the cursor/pointer visit either of the last 2 cases, after evaluating the 1st 2, in order to evaluate whether no case is satisfied.

WAIT WINDOW j_andor+[   !]

before the DO CASE and see what value j_andor has. If it is not equal to [OR] no CASE of this do CASE will be satisfied.

>I can appreciate that may be so but I'd have thought that it doesn't "know" in advance what's in the next case, so needs to visit it to evaluate. But this does 2 cases, neither of which is satisfied, then just jumps out of the CASE statement, without checking the other cases. How can this be?

Is it possible that there was some synchronization issue between the code and the object file?
What happens if you recompile all?
What happens if you add WAIT WINDOW in all CASE statements?

do case   && journey's
   case empty(j_start) .and. empty(j_end) .and. empty(j_andor)
        WAIT WINDOW [1]
        * do nothing
   case j_andor="OR" .and. !empty(j_start)
        WAIT WINDOW [2]
        * but test that both times are not empty
        if empty(j_end)  && ignore the OR
           expr=expr+".and."+ opjrny+j_start
        else
           expr=expr+".and. ("+opjrny+j_start+".or." ;
                     +opjrny+j_end+")"
        endif

   case j_andor="OR" .and. empty(j_start)
        WAIT WINDOW [3]
        * ignore the OR
        if !empty(j_end)
            expr=expr+".and."+opjrny+j_end
        endif
   case empty(j_andor)
        WAIT WINDOW [4]
        if !empty(j_start)
           expr=expr+".and."+ opjrny+j_start
        endif
        if !empty(j_end)
           expr=expr+".and."+ opjrny+j_end
        endif
OTHERWISE 
        WAIT WINDOW [5]
endcase

O! BTW it is possible that some CASE to be satisfied, but not IF in it. Par example if j_ndor ==[OR] and EMPTY(j_start) BUT not empty(j_end)
