Considerations
Note the following facts:
- The order of the pattern lines is important because the first matching pattern line is used to build the return code value.
- Empty pattern strings (“ˮ) are ignored by the pattern matching procedure.
For example, the following is a valid pattern sequence. The first line is more restrictive than
the second line.
“625 “User * missing = 104
“ “User * missing = 102The following pattern sequence is formally valid, but the second pattern line is never used.
Because the first line is more general, it is always matched first.
“ “User * missing = 102
“625 “User * missing = 104
