Psider is a double-deck solitaire for Psion Series 3 type machines. Unlike most
solitaires, it provides opportunities
to overcome bad luck in the deal. The program features an unlimited
undo facility offers move suggestions and can save challenging games to
disk. The semi-automatic mode is ideal for palmtops, as it enables you to
play using single keystrokes. Because Psider uses the entire screen it also
shows you the current date/time and link/battery status.
Psider is written in OPL, the built in interpreter language on the psions.
I used some of the tricks mentioned in the psionic files. One is to misuse
the icon bitmap to store the card face images instead of using separate files
- the drawcard and multibitmap
programs are used for this purpose.
