Description

The reserved word `import' in the import part of a program makes the program import an interface.

The `in' above tells GPC to look for the module in the specified file; otherwise the file name is derived from the name of the interface by adding first `.p', then `.pas' -- which only works if the name of the exported interface coincides with the file name.

The symbol `=>' denotes import renaming: The entity which is exported under the name `baz1' by the interface `bar3' will be known under the new name `glork1' in the program.

The `only' qualifier means that only the listed identifiers will be imported from the interface. Renaming works together with `only', too.

There must be at most one import part in a program.

The interfaces needn't be exported by Extended Pascal modules but may be UCSD/Borland Pascal units as well.

Conforming to

`import' and modules in general are an ISO-10206 Extended Pascal extension.

GNU Pascal does not yet support `qualified' import.
