You didn't say if you are running DOS or Windows version of FoxPro 2.6. Either of them should wait for external program to finish if RUN command was used w/o /N switch (FPW). If it still doesn't wait even w/o /N switch or you don't want to use that switch, than you can try following:

1. FPD 2.6 or FPW 2.6: Create a flag file at the start of VFP application and close at the end. In FP 2.6 check if you can open it. As long as it exists and you cannot open it, VFP app is still running.

2. In FPW 2.6 you can call Win Api Findwindow function to check if VFP app is still running.

SET LIBRARY TO home()+"FOXTOOLS" ADDITIVE
lnCall16 = RegFN("FindWindow", "L@C", "L")
lcAppTitle = "My VFP Application"
lnHWnd =  CallFN( lnCall16, 0, @lcAppTitle )
IF lnHWnd > 0
	* VFP application still running
