You're passing a reference to a reference to a GLOB.  The fact that  
the filehandle is in a scalar means that it is already a reference.

$ perl
pipe ($foo, $bar);
print '$foo is a '.ref ($foo)."\n";
print '\\$foo is a '.ref (\$foo)."\n";
^D
$foo is a GLOB
\$foo is a REF

So, don't put the \ in front of $mainprogread and $mainfractread in  
the call to updateprogressb().
