I have just migrated all my files from vfp 6.0 to vfp 9.0. The change went on smoothly except for 2 modifications I made: included "SET ENGINEBEHAVIOR 70" in the start up program and placing commas between explicitly defined variables in my programs (e.g. PUBLIC var1, var2, ... etc).
However, after compiling my project into exe, the exe file cannot run on workstations that don't have vfp 9.0 installed on them. The start up program is the same that I use on vfp 6.0 and used to work. Does the READ EVENT command still work in vfp 9.0? Here is the main start up program:

CLOSE TABLES ALL
CLOSE DATABASES

SET EXCL OFF
SET TALK OFF
SET DATE TO BRITISH
SET CENTURY ON
SET MARK TO
SET DELETED OFF
SET REFRESH TO 10,5
SET LOCK ON
SET BELL OFF
SET ENGINEBEHAVIOR 70

PUBLIC gcoldfilter, pvUsername, PvUsercode, pvItemopen, pvCount, pvEnrol_date, pvDate_inf, pvlast_visit

pvUsername 	= ALLTRIM(SUBSTR(SYS(0),(AT("#",SYS(0))+1)))
pvItemopen 	= 1
gcoldfilter 	= ""
pvEnrol_date 	= {}
pvDate_inf 	= {}
pvlast_visit    = 0

CD "\\mtwapa2\data\data\Database Management System\"

OPEN DATABASE (CURDIR() + 'Databases\mtwapa')

WITH _VFP
	.VISIBLE = .F.
	.CAPTION="IAVI Database Management System"
ENDWITH

_SCREEN.Icon = (CURDIR() + 'Other Files\iavi Icon.ICO')

DO FORM (CURDIR() + 'forms\log form.scx')
