SET VIRTUAL
LAS\SET VIRTUAL ON|OFF
LAS\SET VIRTUAL CHECK|NOCHECK
First command enables or disables the buffering of spectra read in
CLASS. ON means that for each spectrum, the header and its data are read
once from file at first need, and then from a memory buffer for subse-
quent needs. OFF means they will be read from file at each need. Default
is ON.
The buffering of spectra (headers and data) is done in memory. The dedi-
cated amount can be customized with the Sic logical SPACE_CLASS. It is
allocated once, at first need. Disabling this buffer (SET VIRTUAL OFF)
also deallocates this memory.
A bug in this buffer handling was present from May2006 to Nov2008. See
the news for Dec08 release at http://www.iram.fr/IRAMFR/GILDAS/ for more
details. Since occurence was small and is difficult to predict, the sec-
ond command enables or disables an error which is raised when the bug
would have been encoutered. This is intended to help users to decide if
they should rerun or not the processing of their data with the latest
CLASS releases where the bug is fixed. Default is NOCHECK.
