Load H Program Package File

∟Load H Program Package File

This section describes how to load an H program package file.

You can use the $load statement to load and execute an H program package with the following syntax:

$load package_name $from "package file location";

When the $load statement is executed, the H system will:

Fetch the H package from the given location. It may return the PackageNotFound error.
Execute all statements in H package immediately.
Make all variables and functions from the H package available under the package name prefix.

Example of loading and using an H package:

$load c $from "circle.h";

write(c.pi); # accessing a variable in package
write(c.area(2.0)); # accessing a function in package
write(c.circumference(2.0));
