185
As an example of this, suppose the decimal value 15 is to be converted into octal. The method
is-
and the resultant value is 17, the octal representation of 15. Now, if the result has 1 added to it,
as with the expression -
the ultima te result is 18. This can be a surprise since the usual octal arithmetic suggests that the
result of 178
+
1 be 208. To get the proper octal result, the procedure is -
Note also that the expression -
still does not yield 20.

This function yields the numeric value in octal representation of an assembled location. The
form is-
.. 1..
!·····II:JF;::: (
{assembled location}
As an example, take the case of the example program at the beginning of this chapter. The
result of-
is 76.
This function can be viewed as a convenient method of determining the address of a symbol, or
of an offset from a symbol.
