There are new commands and variables in Luna's scripting language.
  See also ASCTABLE.LUS etc. about this

  -----------------------------------------------------------------

 ù Variables can be created, which are integers, i.e. they have no 
   fractional/decimal parts, and range in value from around -2 billion to 
   +2 billion.
   A variable of this kind must always start with a letter and end with a 
   '%' (percent) character.
   This variable is case sensitive, i.e. a% is not the same as A%!

   Example: a%
   Value of the variable: 0

 ù On its own this is, of course, not very useful, which is why one can
   assign values to them.

   Example: a%=3 
   Content(value) of the variable: 3

 ù One can also calculate with these variables.
   Example: add a%,5
   Content(value) of the variables: a%+5; if a% is 3 beforehand, then a% 
   after the operation is 8.
   
   One can also perform indirect calculations:
   b%=add(a%,5)
   Here the result is not passed to the variable a%, but to the 
   variable b%. There are also other return posibilities.
   
   Example: keypress(add(a%,4),0)

   All four basic arithmetic functions are available for this:
   
   add, add()
   sub, sub()
   mul, mul()
   div, div()   


 ù One can also have loops in a script, which may be nested within each 
   other (with different counter variables).

   Nesting can be up to 32 levels deep.

   Example:

   for a%=1 to 2
     for i%=4 to 5
     next i%
   next a%


 ù Furthermore there are now the possibilities of fast output for text 
   and numerical values. The cursor will be placed at the end of the 
   output string.
   
   Example: tput a% 
       or  tput "Text"


 ù One can also ascertain the ASCII-value of a character.

   Example: a%=asc("W")
   
   a% will then contain the numerical value of the ASCII character 'W'.
