/* LowRunAppleScript compiles and runs an AppleScript
provided as text in the buffer pointed to by text. textLength
bytes will be compiled from this buffer and run as an AppleScript
using all of the default environment and execution settings. resultData
must be non-NULL, and should have been previously initialised, for example
with _hs_initNull. The result returned by the execution
command will be returned as typeUTF8Text in this descriptor record
(or typeNull if there is no result information). If the function
returns errOSAScriptError, then resultData will be set to a
descriptive error message describing the error (if one is
