How do I pass a command line parameter to a Dos Foxpro 2.6 executable from Visual foxpro. The below code does not work.

prmstartdate = date()-15
prmenddate = date()
! /n C:\work\acct\acct05.exe prmstartdate prmenddate

Receiving program.

Param prmstartdate, prmenddate


Problem is the values in the variables are displayed as prmstartdate and not the value.

Any help is appreciated.
Thank you in advance
