Language Overview - Types and Variables
JGrafchart supports four primitive data types: boolean, integer, real, and
string. All primitive data types exist as ordinary variables, inputs, and outputs.
-
Variables receive their values from the application.
Normally they can be both read from and written to but they can
also be configured as constants to prevent writing.
-
Inputs receive their values from the external environment.
They can be connected to I/O cards, input sockets, etc.
Inputs can be read from but not written to from the application.
-
Outputs receive their values from the
application and transmit these values to the external environment.
They can be connected to I/O cards, output sockets, etc.
Outputs are normally only written to but reading is also allowed.
