Opening a known file name

Dear Mentors
I am able to save and restore a mem file using Getfile function but
It makes me select a file from a specified folder even if there
is only one such file nd you already know its name?
Is there a way for open a file without the complete dialog?
Ex file myarrrays.mem
as in Fopen(c:\hmgstorage\myarrays.mem instead of getfile(c:\hmgstorage\myarrays.mem) or some such function
Thanks for looking at my queery.

Thanks for the reply but restore from cannot recall array memvars according to the
Clipper reference. "Arrays and local variables cannot be SAVEd or RESTOREd."
I think there is a function in Harbour somewhere but I can't find a description of it. HB_restore or something like that.
If anyone knows the document describing it please post a reply.

I'm using such a trick to save array in .mem file:
Code: Select all
cTemp := "{ || aArrayToSave := " + hb_valtoexp(aArrayToSave) + "}"
save all like cTemp to "c:\hmgstorage\myarrays.mem"
and a piece of code to restore:
Code: Select all
if file("c:\hmgstorage\myarrays.mem")
BEGIN SEQUENCE with {|e| break(e)}
restore from ("c:\hmgstorage\myarrays.mem") additive
if type(cTemp) <> "U"
eval(&cTemp)
endif
END SEQUENCE
endif

Well! that's some trick. Its going to take me a while to understand but I'll give it a try.
BTW Where are all those HB functions described? I have seen list of them but no reference to use.
Thanks
