That is NOT conforming '85 Standard code.  Are you certain that is what the
test have?

The ADD is a "conditional" format of the ADD statement which may NOT be
nested in the ON EXCEPTION phrase of the CALL statement.  If there were an
"END-ADD" then it would be OK.

The "normal" problem (and possibly what the original post was getting at) is
when two statements have the same conditional type phrase, e.g.

If A > B
  Add +1 to whatever
    On Size Error
        Compute This = That + 1
      Not On Size Error
         Display "Where does this go?"
     *> what goes here?
Else ...


If the next source line after the display is an "END-COMPUTE" followed (I
think) by an END-ADD, then all is "ok". However, to get the NOT ON SIZE
ERROR to "match" with the ADD rather than the COMPUTE, and END-COMPUTE
*must* be coded.
