 Posted: Fri Jun 25, 2004 1:58 am    Post subject: leading subscripts or superscripts I'm trying to create an equation which includes a sequence enclosed with vertical lines (cardinality) but where the left hand line is preceded by a subscript indicator. There's no problem with a trailing subscript indicator but a subscript in that position has a different meaning in this context. Can anyone suggest how OOMath might be persuaded not to consider the leading "_" as an error? _2 widehat left none lline %phi%psi rline right none Any help much appreciated.

For subscripts on the left, try with lsub:
 Code: A lsub b

 Code: {left lline sequence right rline }lsub{index}

Definitively, friday I was asleep:
 Code: {widehat left lline %phi%psi right rline}lsub 2

The "none" command is not necessary...
