---++ Description:

This subroutine is called to separate a filename into its name and extension parts. All parameters are required, if any are missing the subroutine will CANCEL.

&lt;filename_part&gt; will contain the filename part (Required). This must be PASSed with Share "Y".

&lt;extension_part&gt; will contain the file extension part, including its leading period (Required). This must be PASSed with Share "Y".

&lt;full_filename&gt; is the full filename to separate (Required).

The subroutine identifies the &lt;extension_part&gt; by locating all the characters after the last period in &lt;full_filename&gt;. If there are no periods in &lt;full_filename&gt;, then &lt;full_filename&gt; will be returned in &lt;extension_part&gt; and &lt;filename_part&gt; will be empty (the entire name is considered the extension). If &lt;full_filename&gt; contains a leading path, that will also be returned in &lt;filename_part&gt;. See [[0LASubrFileSplitPathname][.FILE SPLIT PATHNAME]] to split the pathname from the base file name.

A 'Data was truncated' error will be returned in .FILE SPLIT FILENAME if the fields you pass are too short to contain either the file name or file extension.
