Using DDE with SAS Software

Question Answer
How do you run some SAS code while using VB? Provided you only want to run a simple program that would normally run in the SAS Program Editor, you can use VB and DDE, like in the following VB code, to simulate the typing of a SAS programmer, e.g.:
	rc = Shell("c:\sas\sas.exe", vbMaximizedFocus)	'start SAS in maximized window
	For i = 1 to 1000	'wait for SAS to initialize
	Next i
	SendKeys "%GP", True	'Globals, Program Editor
	SendKeys "{%}let macrovar = 1234;~", True	'set SAS macro variable
	SendKeys "dm 'af' af;~", True	'run AF application
	SendKeys "%LS"	'Locals, Submit
	SendKeys "%GP", True	'Globals, Program Editor
	SendKeys "endsas;~", True	'Exit SAS
	SendKeys "%LS"	'Locals, Submit
This is the same as starting a SAS session, typing the following Base SAS code in the Program Editor, submitting the SAS code, which also ends the SAS session after the AF Frame application has completed:
	%let macrovar = 1234;
	dm 'af' af;
