from your IDE or the command line. </p> <p>If you use an IDE, import the <filepath>bld.inf</filepath> file

of the example into your IDE, and use the build command of the IDE. </p> <p>If

you use the command line, open a command prompt, and set the current directory

to the source code directory of the example. You can then build the example

with the SBSv1 build tools with the following commands: </p> <p><userinput>bldmake

bldfiles</userinput> </p> <p><userinput>abld build</userinput> </p> <p><xref href="GUID-793A5EF9-CC16-5EEB-9011-6431EA76EB15.dita">How to use bldmake</xref> and <xref href="GUID-B6B54E07-3B34-5D5C-8815-93383FA8FB4B.dita">How to use abld</xref> describe
