When I get a program here it will only run if it is in the same location as the programmer had it. I was wondering if there is any way to make a BAS file load files first from its own directory. If the programmer has to hardcode paths it really is tedious to have to save the files on the same drive or edit the file to hardcode the paths. I guess I am just used to dos that would assume the file and sub directories relative to the program starting folder. It tend to make for a mess of the folder structures or forces me to put programs on a limited Flash drive a: Maybe this was covered before I can't remember or find it here in search. Sorry if this is all well-known.

What platform? For the Pico:-

Quote ? MM.INFO(PATH) Returns the path of the current program or NONE if called after a NEW or EDIT Command

Then you could try ./file for the current directory and ../file for the one above as they are relative to that.
eg LIST "./file.txt"

I am having the most success by recording the path to the program on startup with

dim progFolder$ = mm.info$(path)

I then use that to convert relative paths to full paths as required.

Thank you both for the info and I will try to figure it out but where can I get the manual that covers all the stuff I have been seeing on the forum for the PICO HDMIUSB I am using? Is there a mostly complete Manual besides the one on geoffg.net? That one is about the VGA variant.

There hasn't been a manual for a while. :) The HDMI and USB stuff wasn't available at that time.

I did this not long ago and I've just added a bit that I missed (HDMI pins) and brought it up to date, I think.

I found an older version of this one so this is nice to see. It goes up to B4 and we are now on RC9 I hope not much has changed from your document. Thanks.

This one goes up to RC8. RC9 is bug fixes. Nothing to add, really.

Obviously, it starts more or less where the current manual(s) end so you need at least one of those as well. There isn't one manual that covers all versions now, it was getting too big to manage.
