Programmer's Guide

• D setMode() and getMode() ........ 584
• setGraph() ........ 587
• setTable() ........ 589

The parameter/mode strings used in the setMode(), getMode(), setGraph(), and setTable() functions do not translate into other languages when used in a program. For example, when you write a program in the French Language mode then switch to the Italian Language mode, the program will produce an error. To avoid this error, you must substitute digits for the alpha characters. These digits operate in all languages. This appendix contains the digit substitutions for these strings.

The following examples show how to substitute digits in the setMode() function.

Example 1: A program using alpha parameter/mode strings: setMode("Graph","Sequence")

Example 2: The same program, substituting digits for those strings: setMode("1","4")
