@ -3260,20 +3260,22 @@ environment variable at assembly time. This could, for example, be used
to store the contents of an environment variable into a string, which
could be used at some other point in your code.
For example, you may want to embed the path to your TEMP directory
in your program. As this is usually stored in an environment variable
called TEMP, this could be coded as follows:
For example, suppose that you have an environment variable \c{FOO}, and
you want the contents of \c{FOO} to be embedded in your program. You
could do that as follows:
\c %define TEMP %!TEMP
\c %define FOO %!FOO
\c %define quote '
\c
\c tmpstr db quote TEMP quote
\c tmpstr db quote FOO quote
At the time of writing, this will generate an "unterminated string"
warning at the time of defining "quote", and it will add a space
before and after the string that is read in. I was unable to find
a simple workaround, so I believe that you will need to allow for
the extra spaces if you make use of this feature in that way.
a simple workaround (although a workaround can be created using a
multi-line macro), so I believe that you will need to either learn how
to create more complex macros, or allow for the extra spaces if you
make use of this feature in that way.
