type: ifstream



The syntax for ifstream definitions is:

ifstream definitions
:=(ifstream, definitions)
@ifstream definitions
@:=(ifstream, definitions)

Note: If you are using the first syntax for variable definitions and want to have more code and/or text following on the same line then simply end the definition with ';'.


The ifstream type is used for input file streams.

Note: If you need to define thousands of variables then := is faster, plus it has useful error messages for unrecognised types.
