Does anyone know anything about changing the the size of
global-string-size in bibtex?  I've had a look around and can't seem
to see anything about it.
Anyway the specifics are bibtex 0.99c in tetex-0.4 package, and the
error message is -
Warning--you've exceeded 1000, the global-string-size, for entry Pham:93
while executing--line 1183 of file abstractp.bst
*Please notify the bibstyle designer*
I have an abstract field and it often exceeds 1000 characters so
idealy I just want to be able to increase the size of
global-string-size.
