Asc - Learn To Code - PlayBASIC Documentation

Asc

Result = Asc(InputString$)

Parameters:

InputString$ = The string you to get the ASC II code from

Returns:

Result = The Asc II value that represents this character

The Asc() function takes the Input string and returns the 8bit ASC II character value that represents the first character within that string.

FACTS:

      * Asc() will only return the ASCII code of the first character in the string, any others will be ignored

      * Asc will return a -1 value if the Input string is Null (the string you passed it was empty)

      * If you want to get the ASCII code of other characters in a string and not just the first character, use the MID() function.

Mini Tutorial:

; Display the ASC code of the "a" character.
  Print Asc("a")

; Display the Asc codes for the string "Hello World"
  S$="Hello World"
  For lp =1 To  Len(s$)
     c$=Mid$(s$,lp,1)
     Print Asc(c$)
  Next lp

; Display the screen and wait for a key press
  Sync
  WaitKey
