Simplified Syntax for Interactive Use

Since input capabilities of cellphones are poor, interactive shells support a simplified syntax for function calls, and automatic output of computed expressions:

• A single Expression will be executed as 'print' Expression, unless it is null:

  m>0.85*23.10 → 19.635 m>use math as m m>m.sin(m.pi/4) → 0.7071067812

• A SimpleFunctionCall calls a function with only string or number literal parameters, and options defined for the function.
  • Unquoted words (sequences not containing white space) on the command line which are not keywords (see appendix * ()) and are not starting with a digit or separator are interpreted as string parameters.
  • Numbers are interpreted as numeric parameters.
  • Options for optional parameters (see section * ()) can be specified anywhere with a preceding slash. If an equal sign follows, the following word or number is assigned to the corresponding parameter. If no equal sign follows, true is assigned to the corresponding parameter.
  • Commas to separate the parameters are not permitted.
  Again, the function result is printed if it is not null:

  m>date  // maps to date() → 2005-02-07 11:03:07 m>dir c:\*.m/r  // maps to dir('c:\\*.m', true) → C:\system\apps\mShell\autoexec.m C:\documents\mShell\Jukebox.m

  Simple function calls can only be used to call functions with parameters which are string or number literals.

SimpleFunctionCall :=   [ModulePrefix] Identifier {SimpleParam | SimpleOption} . SimpleParam :=   SimpleChar {SimpleChar} | StringLiteral | NumberLiteral . SimpleOption := '/' (IdentifierChar | Digit) ['=' SimpleParam] . SimpleChar :=   (printable ISO-8859-1 char except white space and '/') .
