{ t54_strcat_strnum: `s + 1' - a string and a number - is a type error.

  A STRING operand makes `+' the concatenation operator, and then BOTH operands
  must be strings or CHARs; a number is not one.  The string on the left is
  what selects the concatenation path, and the number then fails the string
  operand test.  Expected: ETypeErr (56) at the `+'. }
program t54_strcat_strnum (input, output);
var
   s : string[8];
begin
   s := 'abc';
   writeln (s + 1)
end.
