You *can* instruct the compiler to not allocate a new variable, but instead to reuse one of the *virtual registers* R0-R15
(accessible in the code as ``cx16.r0`` - ``cx16.r15``) for the parameter. This is done by adding a ``@Rx`` tag
to the parameter. This can only be done for byte and word types.
to the parameter. This can only be done for booleans, byte, and word types.
Note: the R0-R15 *virtual registers* are described in more detail below for the Assembly subroutines.
Here's an example that reuses the R0 and the R1L (lower byte of R1) virtual registers for the paremeters::
