In order to allow more people to benefit Psion48 power, I have begun to develop a new application with the same goals but in Java. Thus this may be used on any machine running a JVM.
For the present I have implemented very few functions, but they are sufficient to test it. You can click HERE or on the link at the buttom of this page to test an applet based on J48 classes.
Only the data types and functions described in the tables below are usable today. Their number will grow in function of the time I will be able to spent for their development. If you are interested in working on this project with me, contact me.
|Reals||Reals are written as usual. |
Integers are preceded by the '#' character, and followed by the radix.
This may be omitted if you want to use the current radix.
Otherwise use 'b', 'o', 'd', or 'h' prefix for (respectively) binary, octal, decimal or hexadecimal radix.
In order to use other exotic radix, use another '#' followed by the radix.
Thus an integer whose value is 194871 may be written #194871d, #574467o, #101111100100110111b, #2F937h or #123456#11
|Add||Adds level 1 to level 2.|

|Div||Divides level 2 with level 1|
|Drop||Deletes level 1|
|Drop2||Deletes both levels 1 and 2|
|Dropn||Reads n in level 1 and deletes the n following levels|
|Dup||Duplicates level 1|
|Dup2||Duplicates levels 1 and 2|
|Dupn||Read n in level 1 and duplicates the n following levels|
|Hex||Defines the current integer radix to hexadecimal.|
|Oct||Defines the current integer radix to octal.|
|Over||Copies level 2 in level 1.|
|Pick||Reads n in level 1 and copies the nth following level and level 1.|
|Prod||Multiply level 1 to level 2.|
|Roll||Reads n in level 1 and move the nth following level and level 1.|
|Rolld||Reads n in level 1 and move level 1 to level n.|
|Rot||Moves level 3 to level 1.|
|Sub||Substract level 1 to level 2.|
