I want to include a "File, Export" option on my (non-VFP generated) menu system while displaying data in a grid.

I've been informed that e.g. a call to

SYS(1500, '_MFI_EXPORT', '_MSM_FILE')

which works well in the development environment ( as do other options to print, import etc) does not work in runtime.

Anyone have any ideas - other than writing my own code??
