John...I think that may be the most erudite and oblique way I have ever been chastised....and I'm still not sure exactly what it was for- thread drift, faulty assumptions about display capabilities for symbols, or laziness in math...*wry grin*

Since 'most' folks use PCs and leave the default fonts in place, I assumed that 'most' would see the symbols.

I go now to put on my hair shirt and find some sack cloth & ashes.

Mea culpa, mea culpa. Mea Maxima culpa
