The command line interface is started by typing FM at the command level. If a KUIP macro named FATMEN KUMAC is found, this will be executed. It is normally used used to initialise FATMEN, and set the current default directory, if required. For example, the following macro could be used by a member of ALEPH:
INIT ALEPH
An example of starting a session using a FATMEN KUMAC for the throng CNDIV is given below. Once the session has been started, commands such as CD and MKDIR can be issued, as shown in the example.
Starting up FATMEN on VM/CMS and issuing a few commands
TYPE FATMEN KUMAC
INIT CNDIV | Name of DD throng
fm | Enter FATMEN
FMINIT. Initialisation of FATMEN package

FAOPEN : for FARZ on Unit 1 opened File CERN FATRZ
Current Working Directory = //CERN/CNDIV
CD GOOSSENS | Go to user's top directory
Current Working Directory = //CERN/CNDIV/GOOSSENS
MKDIR DCF | Make the DCF subdirectory
FM>
At this point a message is sent to the FATMEN service machine and since the actual creation of the subdirectory occurs asynchronously, one should wait a certain time before entering further commands which would use the sub-directory just created.
Although entries may be made by specifying the full pathname, it is good practice to first create the desired directory structure to avoid warning messages from internal ZEBRA RZ routines. In fact new experiments are strongly recommended to adopt a convention for file and directory names, and to create their directory tree before cataloging files in the FATMEN system.
