The PROJECT Command

The PROJECT command has two purposes:
1) It is used to define a project name of 1 to 8 characters. This name appears on the upper right-hand corner of the screen and printouts. It is also used to form file names when they are omitted from certain commands. For example,
This defines the project name as "ABC" and reads the Geometry File "ABC.GF". The project name is also carried in a system variable named PROJECT.
2) It can be used to manage subdirectories for project files. When used for this purpose, the first parameter always contains at least one back slash (\) -- except for one special case noted below.
It is assumed that there is a master project directory in which individual project directories are located. Optionally, there can be a subdirectory within the individual project directory which contains all of the files relevant to GHS. For example, suppose that the master project directory is C:\PROJECTS. Then, within this directory, there may be project subdirectories such as 9701, 9702, etc. Within each of these subdirectories there may be a subdirectory for GHS files, say GHSDAT. The directory structure would look like the following:
This structure could be created by the following two PROJECT commands:
Of course, it could also be created by operating system commands.
Once the directory structure has been established, the same PROJECT command can be used to change to the data directory. In other words, the new directory is created automatically if it does not exist, but in any case the result is to make the given directory the current or default directory.
If issued from the keyboard, the above commands will also prompt for a project name. If you do not want a project name, simply press Enter. You can also supply the project name as an additional parameter. For example,
This would create and/or change to C:\PROJECTS\9702\GHSDATA and also define the project name as "INTACT".
Another automatic feature when this PROJECT command is issued from the keyboard appears if there are any files in the project data subdirectory with extensions of ".RF", in which case their names will be listed on the screen before the prompt for the project name appears. This makes it easy to pick a project name by pressing the up arrow key and moving to the desired file before pressing enter. Once the project name is defined in this manner, it is only necessary to give the EDIT (F4) or RUN (F5) command and press Enter to edit and Run the file respectively.
After a project master directory has been established, a particular project subdirectory can be selected interactively by giving the command in the following form:
Note that the parameter must end in a back slash. This command first changes to the master directory C:\PROJECTS; then it lists the subdirectories and prompts for the subdirectory name. At this point the name can be typed in or the up arrow can be pressed to pick a project subdirectory from the list. If a new name is typed in, a new subdirectory will be created.
When any of these project directory operations are performed, the program remembers the name of the project master directory, subdirectory and data directory name (if any). Thereafter, these names are implied when omitted. For example,
PROJ \9702
Assuming that the previous commands have been issued, this will change to C:\PROJECTS\9702\GHSDATA.
Similarly, the command
 will change to the last-used project subdirectory and (optionally) data directory.
And, finally, a special case is the PROJECT command without parameters:
This changes to the last-used master directory and prompts for the project subdirectory to be entered.
The program "remembers" project directory names by recording them in a special file named GHS.PRJ which is located in the program directory. While it is not ordinarily necessary to do so, you can erase this file (causing the project directory names to be "forgotten") by the command,
