slow var to fld trick?

[Michael Walas]

I have a long handler that puts the contents of 12 different variables
(each containing about 15,000 chars) into 12 different flds.  It takes
25 seconds for the handler to run on my 6100 Mac running MetaCard 2.2.5
If I take out the 12 lines of the above, the handler runs in less than 1
second.  I've tried different fld properties but I can't speedup the
"put var into fld myfield"  Anybody know any tricks to speed this up?
