If the first 4 characters of the device name are the string '<TT>tape</TT>' (case independent), it will be assumed to be a logical tape name. The environment variable of the same name will then be used for the logical to physical name translation. Otherwise, the name will be assumed to be a physical name. <P> The name of a tape device may contain the host name in which case a remote device will be accessed. This will work only if the MIDAS tape-server has been installed. The full name is then given as '<TT>host:device</TT>' <I>e.g.</I> for a device on a UNIX system <TT>ws1</TT> it could be '<TT>ws1:/dev/nrst8</TT>'. For access to local devices the physical device name can be given directly. When writing on a tape device, it must be set to <I>write enable</I> either by inserting a write ring or changing a switch on the cartridge. <P> A single file can be specified by including its extension otherwise a name is assumed to be a file prefix. When a file prefix is used the full file is made up of the prefix, the four digit sequence number and the file extension '<TT>.mt</TT>'. <P> <HR> <!--Navigation Panel--> <A NAME="tex2html2073" HREF="node123.html"> <IMG WIDTH="37" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="next" SRC="icons.gif/next_motif.gif"></A> <A NAME="tex2html2069" HREF="node121.html"> <IMG WIDTH="26" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="up" SRC="icons.gif/up_motif.gif"></A> <A NAME="tex2html2063" HREF="node121.html"> <IMG WIDTH="63" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="previous" SRC="icons.gif/previous_motif.gif"></A> <A NAME="tex2html2071" HREF="node1.html"> <IMG WIDTH="65" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="contents" SRC="icons.gif/contents_motif.gif"></A> <A NAME="tex2html2072" HREF="node216.html"> <IMG WIDTH="43" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="index" SRC="icons.gif/index_motif.gif"></A> <BR> <B> Next:</B> <A NAME="tex2html2074" HREF="node123.html">File naming</A> <B> Up:</B> <A NAME="tex2html2070" HREF="node121.html">Conversion between FITS and</A> <B> Previous:</B> <A NAME="tex2html2064" HREF="node121.html">Conversion between FITS and</A> <!--End of Navigation Panel--> <ADDRESS> <I>Petra Nass</I> <BR><I>1999-06-09</I> </ADDRESS> </BODY> </HTML>
