Peggi,
Q1) Has anyone run POS exclusively on a USB drive?
A1) I have run the POS software from a folder on a RAM drive for demo purposes with no problems. Depending on your system / RAM dive the program may run a little slow when using features that heavily access the disk storage. Other than that the POS doesn't care if it is run from a RAM drive as long as it is larger then 50 meg.
Q2) Is there a simple way to zero out all items in a stock table, and then use it to check/verify inventory, and create a new stock table for a following year?
A2) This depends on what you mean by "zero out." If you mean to completely erase the stock table so that it has no listing for any item, it is completely empty, then you can just delete the two files in your POS folder that start with the file name you gave to your register file when you created it (like MYSTORE ) and end with the extension .TBL and .IDX (example MYSTORE.TBL and MYSTORE.IDX ) If you do this you will have NOTHING, no stock table whatsoever.
However if you want to erase only the # SOLD, VALUE SOLD, and INVENTORY columns in the stock table then do the following.
From the main POS.EXE menu go to "7. CLOSE" and then choose option "2. Close register/Print/Erase/Exit" and then when you are offered the option to "Erase the merchandise data" select "YES." This will set all the values in the # SOLD and VALUE SOLD columns of the stock table to all zeros.
To reset the inventory values use the INVENTOR.BAT program and create an inventory file without entering any counts. Now from the main POS.EXE menu go to "3. File maintencnce" then "9. Read inventory file." When you read an inventory file the program will first set all inventory counts in the stock table to all zeros and then replace them with the counts from the inventory file, but since you did not enter any counts into the inventory file there will be nothing to add to the inventory once it has been erased.
