providing, on said device, one or more configuration values to be included in said conditional expressions, at least some of said configuration values defining conditions for transitions between said plurality of operational modes; and

during execution of said program, providing as input to said conditional expressions, values representing one or more states in which the device is operating.

2. The method according to claim 1, wherein said configuration values are included in the code of said computer program.

3. The method according to claim 1, wherein said configuration values are included in a configuration file stored on said device.

4. The method according to claim 1, wherein said configuration values are downloaded from a remote location with which the device is capable of communicating.

5. The method according to claim 1, wherein at least some of said configuration values define parameters to be applied in a given operational mode.

6. The method according to claim 1, wherein at least some of said configuration values are associated with a display of said device.

7. The method according to claim 6, wherein at least some of said configuration values define one or more minimum or maximum values that will override formatting native to a document displayed on said display by said computer program when said computer program is operating in a given operational mode.

8. The method according to claim 7, wherein said configuration values include one or more of a maximum font size, a maximum number of text columns, whether or not images should be displayed, minimum text contrast, and a set of rules for table reformatting.

9. The method according to claim 8, wherein the rules for table reformatting include shifting one or more columns in a table that falls outside a display area such that the shifted one or more columns are positioned visibly within the display area in an additional row directly adjacent to the row from which the shifted column originated.

10. The method according to claim 1, wherein said values representing a state is one or more of an environment variable, and type data.

11. The method according to claim 10, wherein said environment variable is indicative of the width of a window displayed on said display.

12. The method according to claim 1, wherein said computer program is a program capable of rendering on a device display a representation of a document present on said device as one of a markup file and a word processing file.

13. The method according to claim 12, wherein said operational modes include alternative sets of rules for the spatial representation of said markup file or word processing file on said display device.

14. The method according to claim 12, wherein said markup file is a file encoded according to a markup language such as SGML, WML, HTML, DHTML, XHTML or XML.

27. The computer-readable storage medium according to claim 1, wherein said configuration values are included in the code of said computer program.

15. A device in which an adaptable computer program is implemented, comprising:

a memory that stores program code containing conditional expressions for selecting one out of a plurality of operational modes for said program, and configuration values associated with said conditional expressions;

an execution unit that obtains and includes said configuration values from the memory and that furthermore obtains values representing one or more states in which the device is operating and executes the conditional expressions in the program code using said configuration values and said state representing values as input to said conditional expressions; and

an output unit that presents output data in conformance with the operational mode selected through execution of the conditional expressions in the program code.

16. The device according to claim 15, wherein said memory stores said configuration values as part of said program code.

17. The device according to claim 15, wherein said memory stores said configuration values in a separate configuration file.

18. The device according to claim 15, wherein said memory also stores configuration values that define parameters to be applied when a given operational mode is selected by said execution unit.

19. The device according to claim 15, wherein said configuration values are associated with a display of said device and said output unit is a display.

20. The device according to claim 19, wherein said configuration values define one or more minimum or maximum values that will override formatting native to a document displayed on said display by said computer program.

21. The device according to claim 20, wherein said configuration values include one or more of a maximum font size, a maximum number of text columns, whether or not images should be displayed, minimum text contrast, and a set of rules for table reformatting.

22. The device according to claim 21, wherein the rules for table reformatting include shifting one or more columns in a table that falls outside a display area such that the shifted one or more columns are positioned visibly within the display area in an additional row directly adjacent to the row from which the shifted column originated.

23. The device according to claim 15, further including a state-detecting unit for detecting and reporting the conditions of the device and display associated with the configuration values.

24. The device according to claim 15, further including a communication unit that can communicate and receive data from other devices.

25. The device according to claim 15, further including an input/output unit that can receive data input from a user corresponding to the operation of the display.

26. A computer-readable storage medium comprising an executable adaptable program instruction, comprising instruction for:

providing in the code of said computer program one or more conditional expressions for selecting one out of a plurality of operational modes for said program;

providing, on said device, one or more configuration values to be included in said conditional expressions, at least some of said configuration values defining conditions for transitions between said plurality of operational modes; and

during execution of said program, providing as input to said conditional expressions, values representing one or more states in which the device is operating.

28. The computer-readable storage medium according to claim 26, wherein said configuration values are included in a configuration file stored on said device.
