The Same Thing In OmniMark

In OmniMark the syntax is different but the general style is the same:

set postalcode to "H3G 1V7"
do scan postalcode 
match (uc digit uc) => part1 " "?
      (digit uc digit) => part2 =|
   set postalcode to part || part2
   output postalcode || "%n"
else
   output "Invalid postalcode: " || postalcode || "%n"
done
