Appendix A. Keywords and Predefined
Constants
Several words are reserved for use by CRBASIC. These words are not case sensitive and
cannot be used as variable or table names in a program. Predefined constants include
some instruction names, as well as valid alphanumeric names for instruction parameters.
In general, instruction names should not be used as variable, constant, or table names in a
datalogger program, even if they are not specifically listed as a predefined constant.
If a user programmed variable happens to be a keyword or predefined constant, a runtime
or compile error will occur. To correct the error, simply change the variable name by
adding or deleting one or more letters, numbers, or the underscore (_) from the variable
name, then recompile and resend the program.
The following is a list of keywords and predefined constants in CRBasic. It is possible to
use a keyword as part of a variable name if there are additional letters preceding or
following the letters that make up the keyword.
