require (Command)
requirepackage [filename]
The require command loads the package specified by the variable name package from the file specified by filename, if it's not already loaded. If filename is not specified, the list of directories specified in the -loadpath option of the set command is searched for a file named package.acl, where .acl is the standard Arbortext Command Language file name suffix.
If the specified package name is not defined after the file is read, the require command will issue an error message and set main::status to 1, indicating failure.
The require command has no synonym.
* 
The require command is just like the require function, except that the function allows expressions.
