/* Function Name: Parse_Command_Line */
/* */
/* Descriptive Name: Parses a stream of tokens provided by the */
/* scanner and screener and produces a list of */
/* trees representing the commands found in the */
/* stream of tokens. The trees are constructed */
/* of nodes of type Executable_Node and are */
/* suitable for use with the Interpret_Commands */
/* function provided by interpreter.c. */
/* */
/* Input: None. */
/* */
/* Output: The function return value is a list of trees where each */
/* tree represents one command found in the input stream. */
/* */
/* Error Handling: Parsing errors are reported immediately to the */
/* user using the facilities provided in error.h. */
/* If an error is encountered, then the function */
/* will return a NULL value for the list. */
/* */
/* Side Effects: Tokens are read from the input stream. Tokens are*/
/* disposed of after use. Error messages may be */
/* output to the user. */
/* */
/* Notes: The SetInput function of the scanner must be used prior */
/* to calling this function to establish the source of */
/* input for scanning, screening, and parsing. */
