>I am trying to implement the ShellExecute function to open a various documents on a system (MS Word docs, pdf, Excel sheets, etc). All file types work as expected with the exception of MS Word docs - they open and then produce a VFP Error #12 Variable '18' is not found. There is no code in the method that contains anything related to an '18'.

Try getting the return result via

lnresult = ShellExecute(0,"open","c:\test.doc","","",1)
