Thanks a lot, using a little bit of your suggestion I have managed a workaround. This involves two activeX script tasks. The first loads the variables and is run before any other tasks. The second saves them and is run after every other task. It seems to work very well. This is the code in the first....

'Load Variables

Function Main()

set pkg = DTSGlobalVariables.Parent

set fso = CreateObject("Scripting.FileSystemObject")

set file=fso.opentextfile("E:\gvsave.txt",1,False) '**Load in previous runs global variables

While Not file.AtEndOfStream '**Take two lines at a time (gv's name and value) until end of file

gv_name = file.readline

gv_value = file.readline

DTSGlobalVariables(""&gv_name)= gv_value

Wend

file.close '** Clean up

Main = DTSTaskExecResult_Success

End Function

.........and the second.......

'Save Variables

Function Main()

set pkg = DTSGlobalVariables.Parent

set fso = CreateObject("Scripting.FileSystemObject")

set file=fso.opentextfile("E:\gvsave.txt",2,True)

For Each gv in pkg.Globalvariables

file.write gv.name & vbcrlf

file.write gv.value & vbcrlf

next

file.close

Main = DTSTaskExecResult_Success

End Function
