 Command parameters are of the following general types: 
  
  Numeric - consists of +, -, ., 0-9, or the Null-number character
  Word    - any characters except blank, Numeric & Metacharacters
  File    - a VAX file specification (no blanks or Metacharacters)
  String  - contains any character except the command Delimiter
  Quoted  - offset with "quote" characters; may contain Metacharacters
  
 Because  of  the  unique  composition of Numeric, Word, and File
 parameters, they may be intermixed on  a  command  line  in  any
 order without confusion.
