SD Cards

SD cards are indispensible when using the HP50g. 256 Mb, the smallest SD card I have ever seen on the market, is more than adequate.
I keep all my programmes in directories (apart from commonly used subouines such as AnyKey) and move the entire directory to the SD card using Filer.
There are then a myriard of ways to retrieve the program directory from the SD card to HOME when I want to use it.
All this means that you can keep HOME memory, the working memory if you like, as free as possible.

Reducing HOME memory.

If you don't have an SD card you can still save about 20k of HOME memory by moving various of the ISO6976 static data structures to ERAN or FLASH memory. The program was designed with this eventuality in mind. To move these data structures run the program PMove from the main ISO6976 menu.
The data structures that are moved are: Name6976 MU6976 M6976Out M6976Menu M6976Edit H6976 Data6976Tags and Data6976

Common Subroutines.

About 10 subroutines are shared with other of my programmes. Normally I keep these in the HOME directory. You are free to use these subroutines yourself.
Use progam HMove from the ISO6976 main menu to do this.
The subroutines that are moved in this way are AnyKey CDisp Elim FNB GetIx LNB LTrn MRcl NPC Rect? Show Trim
