          SYNTAX  An instruction issued to a computer must be precisely in a 
          ======  form that the computer can work to. This form is known as 
          SYNTAX and covers spelling, spaces, punctuation etc. Any deviation 
          from correct SYNTAX in Mallard Basic will be greeted with the 
          message "Syntax error", and the offending line will be presented in 
          EDIT mode for correction.

              Very often, even when one has some experience in BASIC, the 
          error is hard to find, but it will be there somewhere. This is a 
          good reason for not making program lines too long and involved.

              Common errors are;

              Wrong spelling of keywords
              Spaces positioned incorrectly
              Incorrect punctuation - semicolon instead of a colon etc.
              Brackets - there must be an equal number of (  and  ) to a line
              Wrong character used - l instead of 1; O instead of 0; B instead  
                                     of 8  etc.

              Some of these errors will be made easier to spot if you follow 
          my rule of entering keywords in lower case. If a syntax error 
          concerns a keyword, BASIC will not then put that word into upper 
          case, so you will quickly see that error.
              There are a number of other error messages and these are covered 
          elsewhere, but the above should be sufficient to show that in 
          programming near enough is not good enough. However you will soon 
          find where you can take liberties and get away with them.

          It must be stressed that a program can be in correct syntax and 
          still not run properly or achieve the desired result, in the same 
          way that a sentence written in English may obey the rules of grammar 
          and yet make no sense.
