User–Defined Variables
All user–defined variable names must satisfy the following requirements:
The first character must be an alphabetical character.
The rest of the name must consist of an alphabetical character(s), digit(s),
and/or an underscore(s) (_).
The maximum number of characters is 16. All characters in excess of 16 are
ignored. Variables that have the same first 16 characters will be regarded as
identical.
Alphabetical characters are case–insensitive. For example, FooBar and foobar
are handled as the same variable name.
You can use user–defined variables in the program without first declaring
them.
User–defined variables are 64–bit floating–point decimal numbers.
A maximum of 100 variables may be included in a program; this includes the
reserved variables, such as clock.
There are no string variables; all variables require a numeric value.
Initial variable values are undefined.
The following are unavailable for user–defined variables.
Reserved word variable names
Constant names
Function names
Keywords (for example, if and marker1)
