Identifiers are arbitrary names of any length given to functions, variables, symbolic
constants, user-defined data types and labels. All these program elements will be
referred to as objects throughout the help (don't get confused about the meaning of
object in object-oriented programming).

Identifiers can contain the letters a to z and A to Z, underscore character “_”, and
digits from 0 to 9. The only restriction is that the first character must be a letter or an
underscore.

Pascal is not case sensitive, so Sum, sum, and suM are an equivalent identifier.

Although identifier names are arbitrary (according to the stated rules), if the same
name is used for more than one identifier within the same scope then error arises.
Duplicated names are illegal within same scope. For more information, refer to
Scope and Visibility.

Here are some valid identifiers:

temperature_V1

Pressure
no_hit

dat2string

SUM3

_vtext… 

and here are some invalid identifiers:
