MOUSE-83

Mouse-83 was described in the book Mouse: A Language for Microcomputers by Peter Grogono [2]. It includes a number of enhancements over the earlier version (Mouse-79):
  • The assignment operator was changed from ( = ) to a colon ( : ), and the order of operands was changed. For example, in Mouse-83, X is assigned a value of 3 using 3 X:.
  • In Mouse-83, a program is terminated with a single $ (instead of two).
  • A mathematical remainder operator ( \ ), which returns the remainder of the quotient of the top two numbers on the stack.
  • Character I/O. Mouse-83 can input a character from the terminal using the operator ?' . A character can be printed to the terminal using the operator !' . An apostrophe operator by itself is used to indicate a character literal (for example: 'C ).
  • Comparison operators ( < > = ) were added to enhance conditional statements.
  • The syntax of macro operators was changed. Within a macro, Mouse-79 referred to its parameters as %A %B %C, etc. In Mouse-83, macro parameters are called 1% 2% 3%, etc.
  • Mouse-83 includes operators to trace program execution ( { } ).
  • Comments in Mouse-83 begin with a tilde ( ~ ) and continue to the end of the line.

Documentation

Interpreters

The Windows binary file was made from the C version, compiled under Windows XP using the Borland C++ compiler. It should be run from a DOS window. To run a Mouse program, type from the command line:

   mouse83 <filename>

where <filename> is the file name of the Mouse program. If no file extension is specified in the file name, an extension of .mou is assumed.

Programs from Mouse: A Language for Microcomputers
