Basically the command to be executed goes in the command field, and
then the system chooses the data fields that it wants to look at.
But it seems rather wasteful. Would it not be more sensible to simply
have "enough" doubles, ints, bools etc for each command, with generic
names ("double_1" for example)
As things stand, every time a new command is added, a few more
variables get added to the struct, to be used once or never every
run....
