*    This procedure wraps the write-the-current-query function
*    of RESULTS for the VAR programmer using sffire("Write4GL").
*
*    The problem is that it doesn't make sense to generate source
*    for those views because they contain widgets. Trying to "run" those 
*    views inside of an OUTPUT statement will cause a hang.
*
*    Let the VAR know that there is a problem.
