+<concept id="GUID-35532303-1316-58CA-90C8-FAB56EE3C1F5" xml:lang="en"><title>version</title><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p> <codeph>version</codeph>  <varname>major.minor</varname> <codeph>[explicit]</codeph>  </p>
+<p>The <codeph>version</codeph> keyword allows a version number to be set
+for a project. The optional keyword, <codeph>explicit</codeph> is used to
+append the specified version number to the <filepath>.exe</filepath> or <filepath>.dll</filepath> output
+file. </p>
+<p>EKA1 will only allow one version of an executable to exist in a Symbian
+platform phone. However, EKA2 supports version numbering. Version numbering
+associates a version number with each executable enabling new and old versions
+of the same executable to be on the device simultaneously. </p>
+<p>The <codeph>version</codeph> keyword takes a major and a minor value separated
+by a full stop. This value is defined as 32 bit, anything exceeding this will
+produce a warning. Failing to enter a value will result in a warning and a
+default value of 10.0 being supplied for binaries built with an EABI compliant
+compiler. Omitting the version keyword altogether will also result in a default
+of 10.0 being applied. The version number can be found at Hexadecimal offset
+70 within the header of the executable file in ROM. </p>
+<p>Usage of the version keyword is optional. One use is to aid eclipsing.
+In order to eclipse a file on ROM successfully the version of the new file
+can be set to a higher value than the version of the file to eclipse. This
+tells the loader that the new file is preferred over the old one. </p>
+<p>See the <xref href="GUID-7F65B69A-6AC1-509C-91E8-9E49ED0BFEC0.dita#GUID-7F65B69A-6AC1-509C-91E8-9E49ED0BFEC0/GUID-124e78dc-2c94-4901-a90b-20ddc2f3ad66">Important
+Considerations</xref> section for more information. </p>
+<p>The loader will show preference to versions that have a major number that
+is equal to the one requested, and of these the minor numbers
+that are higher are preferred. The loader can assume by the version number
+that the API is compatible, while also being the most up to date version available. </p>
+<p>If the above is not available the loader will look for DLLs with a higher
+major version number than the one requested. Of these it will select the one
+with the lowest major number and the highest minor number. If the executable
+requests exports that no longer exist in this DLL, then the loader cannot
+use it. </p>
