COMMAND NAME
	write -- write an augmented error information strcuture to a file
SYNOPSIS
	write [filename]
DESCRIPTION - USAGE

This command will write a new AllErrorInfo structure to a file. If the
argument "filename" is present then the structure is written to "filename,"
otherwise the user is queried for the filename.  
If the argument filename is ommitted, the user is queried for a valid file 
name.  The default name for the file is the name of the last file read or 
written with the extension ".aer".

Warning:
This routine does not check to see that the filename ends with ".aer".  Some
programs that use IDL structures may require the ".aer" extension.  Users 
are therefore encouraged to use the ".aer" extension when writing out
AllErrorInfo structures.
