The setpos alias is used to redefine the current position to some
specified value. It is an alias to the zero command which is designed to
avoid the user having to remember the definition of the zero
angle.
The syntax for the setpos alias is:
setpos motor value
This will redefine the zero angle of motor so that
it is at position value.
For example, the command setpos s1 100 will redefine the
zero angle so that the current position now reads 100.
NOTE that the following information is not required to understand the
usage of the command but is included for completeness:
The alias definition is:
zero %1 @(%1.zero)+@(%1)-%2
The argument @(%1.zero) will use the current zero angle for the motor
specified by %1 and the @(%1) will use the current position for the
motor specified by %1. For more information about the syntax of
these @(...) variables, see the How to use and command-line variables
guide.
