arguments.mlm

/* 
 * You may run this MLM with: $ arden2bytecode -r arguments.mlm
 * However, to pass arguments, use the -a flag of Arden2ByteCode. The string 
 * following the -a flag must be a valid constant Arden Syntax expression. 
 * Otherwise a parsing error will occur. 
 * To be a valid Arden Syntax expression, a string must be surrounded
 * by quotes which, in turn, must be properly escaped when being
 * passed on the command line.
 * Passing the string "argument 1" would be: 
 * $ arden2bytecode -a "\"argument 1\"" -r arguments.mlm
 * 
 * Windows Command Prompt:
 * $ arden2bytecode -a (3.5,2) "5 WEEKS" 123 "\"Jane Doe\"" -r arguments.mlm
 * 
 * Bash:
 * $ ./arden2bytecode -a '(3.5,2)' '5 WEEKS' 123 '"Jane Doe"' -r arguments.mlm
