Syntax

Set returnVal to MyScriptFunc(  ) of me

Description

me is used to specify a script-defined subroutine or property, to distinguish it from the properties or functions of other applications that the script uses. me is most often used in the form propertynameorfunctionname of me. In the following code, the me predefined variable is used inside a tell...end tell statement block to identify the getMegabytes function as a script subroutine, not a Finder command. If you left out the of me part of getMegabytes(b) of me then the script would raise an error, because it would tell the Finder to call its getMegabytes handler, but the Finder doesn’t define this command. In the absence of the me or my constants, all commands inside of a tell...end tell block are directed to the application targeted by the tell block or to scripting additions (Chapter 7discusses tell blocks). The script identifies getMegabytes as its own subroutine, which is an elegant way to call this useful routine anywhere you want in the script:

tell application "Finder"
   set b to largest free block -- returns free memory block as bytes
   set mb to getMegabytes(b) of me
   display dialog mb
end tell
(* subroutine definition; converts bytes to megabytes *)
on getMegabytes(byteVal)
   if (class of byteVal) is in {integer, real} then
      set megValue to (byteVal / 1024 / 1024)
      return megValue
   else
      return 0
   end if
end getMegabytes
