1GENERAL: parameter - give names to command line parameters for macros

Usage: parameter <variable1> {<variable2>}

In a macro, parameter changes the default command line parameter names
"p1", "p2",... to the variable names <variable1>, <variable2>,... The 
"parameter" command must precede any other commands in a macro (except
"var" commands) and cannot be used interactively.
