Hi Robert,

There are a couple of solutions you might consider, both involving calls to the SHELL32.DLL. The first would be to use FindExecutable to locate the file, then use the RUN command. That's in line with what you're trying to do. However, another (and in my opinion, better) solution would be to use ShellExecute to run the program. Anyway, here are both:

DECLARE INTEGER FindExecutable IN Shell32;
  STRING @lpFile, STRING @lpDirectory, STRING @lpResult
DECLARE INTEGER ShellExecute IN Shell32;
  INTEGER hwnd, STRING @lpOperation, STRING @lpFile,;
  STRING @lpParameters, STRING @lpDirectory, SHORT nshow
* lcfile is the file to be found or execute
* lcpath is the working directory or path
lcbuffer = SPACE(261)
lnresult = FindExecutable(@lcfile, @lcpath, @lcbuffer)
lcop = 'open'
lcparms = ""
lnresult = ShellExecute(0, @lcop, @lcfile, @lcparms, @lcpath, 1)

In either case of value less than or equal to 32 is an error. If the file isn't associated with an application, 31 is returned.

hth,
