move    d s     // stores the value of s in d

add     d s t   // calculates s + t and stores the result in d
sub     d s t   // calculates s - t and stores the result in d
mul     d s t   // calculates s * t and stores the result in d
div     d s t   // calculates s / t and stores the result in d
mod     d s t   // calculates s mod t and stores the result in d. Note this
                // doesn't behave like the % operator - the result will be
                // positive even if the either of the operands are negative

round   d s     // finds the rounded value of s and stores the result in d
trunc   d s     // finds the truncated value of s and stores the result in d
ceil    d s     // calculates the ceiling of s and stores the result in d
floor   d s     // calculates the floor of s and stores the result in d

min     d s t   // calculates the minimum of s and t and stores the result in d
abs     d s     // calculates the absolute value of s and stores the result in d

// boolean arithmetic uses the C convention that 0 is false and any non-zero
// value is true.

This is a sample timer command set, alternating between 1 for 1 tick (0.5s), then off for 2 ticks (1s).
