It should be noted that while the code generated in <strong>Pascal</strong> for the function<br />
LocalFNC in the preceding example may be slightly less compact than the<br />
above hand-coded version, there will be an overhead in the cost of<br />
performing the CXP/RXP through My_FNC, relative to the BSR/RET<br />
which would be performed for the call to LocalFNC. The difference<br />
between the two methods may in consequence be very small.<br />
