Mid$
ReturnString$ = Mid$(SourceString$, Position, [Length=1])
 
Parameters:

    SourceString$ = The string you want to copy characters from
    Position = The first character (from the left) of where to start grabbing characters
    [Length=1] = The optional number of characters to grab, defaults to 1
Returns:

    ReturnString$
 

      The Mid$() function allows us to copy single character or run of characters from a source string to another string. The characters are copied in a left to right order, starting at the position parameter and ending at Position + Length.

      It's important to understand that MID$ does not remove the characters from the Source String, it just copies the selection of characters from the source string into a new string result.



FACTS:


      * If either the character position or copy length are outside the source strings length, the returned string fragment will be clipped to length of the source string.

      * The Mid$() function always returns a string. So if you want to read the strings ASCII values directly you should use MID() function.




Mini Tutorial:


  
  Number$="1234567890"
  Print Mid$(Number$,5,2)
  Print Number$
  Sync
  WaitKey
  


      In this example, the MID$ function will copy two characters from the string number$ starting at character five (from the left hand side). So it will output the characters 56 to the display.

      This example would output

  
  56
  1234567890

  SourceString$= "<---Play Basic--->"
  
; Grab the 10 characters from SourceString$ stating at charcter 5 using Mid$(), then
; place those Characters into the variable Grab$
