Execution of LOAD functions is controlled by a series of LOAD commands, which are fully described in chapter LOAD Commands.
The line at the bottom of the screen is used to enter commands and begins with '==>'.
LOAD commands consist of a command word and a series of - partly optional - parameters. Only the first four characters of a command word are significant. Lowercase characters in the command are converted into uppercase ones, apart from file names and other parameters enclosed in single quotation marks:
==> run item.inst k z is converted into RUN item.inst K Z
A series of LOAD commands can also be called by a key. The current key setting is displayed below the system line. Example:
1=Help 2=Reset 3=End 4=Print 5=Run 6=Next 7=Up 8=Down ...
This display depends on the chosen language. The command words themselves are always English.
As far as the labeled keys are concerned, the following may be of some importance to the LOAD user: the 
key for calling the HELP function and the 
and
keys for scrolling the screen. The keys for the editor functions (insert, delete, copy line etc.) are described in the platform-specific User Manuals.
If LOAD is running at a terminal that does not have soft keys, both the soft keys and the Help, scroll, and editor keys are simulated by the keys 
, 
, ...,
. LOAD then displays the current settings of these keys below the input area.
