Free datecalc for java software for pda

Programming calculator. You can write programs for stack machine (with simplified Java like instruction set). Program consists of one or more procedure which can be nested. It is possible to access variables of top procedure (like in Pascal). You can execute program ste-by-step and inspect stack and variables in debugger. Input of commands and thier operands is optimized for mobile phone. This calculator is using floating point arithmetic with quadra precision (64 bits for both mantissa and exponent) implemented by Nikolay Klimchuk.
Main features:
- PCalc keeps in database all your programs. A program consists of main procedure and may be some subprocedures. Program may have input parameters. The values of these parameters will be asked when program is started. Access to the parameters is performed using input instruction.
- PCalc provides stack-based language (like Forth). Operands are pushed on stack and operations are performed with top elements of the stack. Temporary results also can be stores in local variables (of self or outer procedure). Stack is also used to pass parameters to procedures and return values. Content of stack after return from main procedure is treated as program result. It is also possible view values of variables of main procedure (if program should return many results it is more convenient to store them in local variables).
- PCalc provides the following groups of instructions: load/store, operators, functions, control flow. Instructions of first three groups do not require extra explanation. Control flow instructions includes procedure call, return, conditional (IF) and unconditional (GOTO) branches. IF transforms control to the specified label if value on stack is zero. Label for these instruction is specified by selecting instruction in the list. Please notice, that when you are inserting new branch instruction it is not yet present in the list.
- PCalc provides wide editing capabilities. It is possible to add/remove/rename any variable/parameter/function. The only restriction is that it is not possible to remove entity which is used. It is also possible to move label (adjusting all branch instruction referencing this label) or change target of particular branch instruction.
- PCalc allows to introduce new variable only when you are specifying operand for STORE. Operand of load method is selected from the list of available variables. It somehow prevents programmer from using uninitialized variables.

Awele is a nice puzzle game where the aim of the game is to collect the biggest number of beans.

Asteroid Zone is a Java 2 Micro Edition (j2me) version of the classic arcade game: your spaceship has ventured into a particularly unfriendly area of space where it must strive for survival by blasting asteroids which threaten to squash it. The ship has a powerful gun, a propulsion system (be careful with inertia !), and can teleport.

StopWatch is a simple application for measuring time with possibility to register several (up to nine) results and suspend/resume measurement.
Notes:
StopWatch works in one of two modes: run mode and inspect mode. In run mode it is possible to register results and in inspect mode - watch them.
To start StopWatch press any of *, 0 or # buttons. StopWatch is now in run mode and digits at the center of the screen shows elapsed time. At the top of the screen there is an identifier of current measure. To register result for this measure (first sportsman if finished) press any button on joystick. The number at the top of the screen is changed to next one and you can register time for the next sportsman. StopWatch is able to register up to 9 results.
It is also possible to register results not in increasing order of measure identifier. To register result of sportsman with number N, press button N.
To suspend measure press # button. To resume measure - press # button. Pause time (time between suspend and resume) is excluded from measurement.
Pressing once again at * button will stop the watch and midlet is now switched to inspection mode. In this mode it is possible to view results of each sportsman either listing them using joystick (LEFT and UP buttons shows result of previous sportsman, RIGHT, DOWN and FIRE - result of the next sportsman), either directly select sportsman by its number using 1-9 buttons.
