[SR-Users] setflag and hash table variables

[Asgaroth]

Hi Daniel,

Thanks for the info, I'm not familiar with $mf.

Is "$mf = $mf | (1 << $sht(core_setid=>$var(ds_setid)) );" functionally 
equivilent to "setflag( $sht(core_setid=>$var(ds_setid)));"?

Can I still use the isflagset function to check if certain flags are set 
when using your alternative approach?
