 support for comparing strings as well :-))
 
 Now table driven to allow the operators
--eq, -ne, -lt, -gt, -le, -ge, ==, !=, <>, <, >, <=, >=
+-eq, -ne, -lt, -gt, -le, -ge, -and, ==, !=, <>, <, >, <=, >=, &
 
 Uses the expected command modifier for integer compares of width 1, 2 or
 4 bytes of .b, .w, .l and the new modifer of .s for a string compare.
