Hi

Struggling through the "bane of my life" gibberish code again that has been my lot to maintain (not mine BTW!)
Have been watching the following CASE in debug (using VFP7 to follow FPD2.6 code). I know that it doesn't satisfy the 1st 2 cases, and watch it skirt these, then it suddenly shoots to the EndCase, ignoring the other two cases. There are 2 similar secytions where it does this too.

Anyone any ideas how this can be?

  case empty(j_start) .and. empty(j_end) .and. empty(j_andor)
     * do nothing
      
  case j_andor="OR" .and. !empty(j_start)
     * 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)
     * ignore the OR
     if !empty(j_end)
        expr=expr+".and."+opjrny+j_end
     endif
     
  case empty(j_andor)
     if !empty(j_start)
        expr=expr+".and."+ opjrny+j_start
     endif
     if !empty(j_end)
        expr=expr+".and."+ opjrny+j_end
     endif
