Leaving a CATCH block empty means that the exception in question is neither handled nor passed forward to callers for handling at a
higher level. Suppressing errors rather than handling them could lead to unpredictable system behavior and should be avoided.
Noncompliant Code Example
try.
if ABS( NUMBER ) > 100.
write / 'Number is large'.
endif.
catch CX_SY_ARITHMETIC_ERROR into OREF.
endtry.
Compliant Solution
try.
if ABS( NUMBER ) > 100.
write / 'Number is large'.
endif.
catch CX_SY_ARITHMETIC_ERROR into OREF.
write / OREF->GET_TEXT( ).
endtry.

When a block contains a comment, it is not considered to be empty.
