Running Script from Syntax

'Begin Description
' There are syncronization problems when scripts are called from syntax: they don't execute 
' where they are supposed to do. Scripts are executed after SPSS has finished running all 
' the syntax, and not at the point where they are called in the syntax.
' This script tries to solve this problem, by reading the syntax in the active syntax window
' and sending it to SPSS for execution. When it encounters a SCRIPT command, it is 
' immediately executed.
' The organization of the entire job is given to this script, not to SPSS, therefore the 
' execution of a syntax containing script calls need to be invoked by launching this script. 
' INCLUDE commands are also handled by the script by loading the syntax file to include,
' and executing it in the same way of the syntax in the syntax window. When the include 
' syntax file terminates, the commands following the INCLUDE command are executed. Nested 
' include files are supported, and the allowed number of nesting levels depends from the 
' script's available free memory.
' In this way, SCRIPT commands also found in an included syntax file, are handled and 
' immediately executed.
' This script acts as an interpreter: it reads every syntax line, and when either the SCRIPT 
' or INCLUDE command has been recognized, it performs the appropriate action.
' Every not recognized command is sent to the SPSS processor.
'End Description

'ASSUMPTIONS
	'A syntax window needs to be opened. The script executes only the code into the 
	'designated syntax window.
	'Parameters passed with the SCRIPT command will be sent to the script to execute, but
	'the script invoked by this command can read the parameters by using the Command$ 
	'function, instead of the objSpssApp.ScriptParameter() method as usual.
	'Either SCRIPT and INCLUDE commands, when placed in a macro definition (that is,
	'within DEFINE - !ENDDEFINE) are ignored, and they won't be executed. Other commands
	'in	a macro definition will be executed as usual.
	
'EFFECTS
	'Allows syncronization between scripts and syntax: now a script called with the 
	'SCRIPT command is immediately executed.
