Latex Subscripts and Superscripts
Syntax $latex Command $$

XML dependently interpret the subscripts and superscripts specified by Command where Command contains the underbar character _, the caret character ^ or both.

Command Output
x^{2y}  x^{2y}
x_{2y}  x_{2y}
x^{y^{2}}  x^{y^{2}}
x^{y_{1}}  x^{y_{1}}
x^{y}_{1}  x^{y}_{1}
x_{1}^{y}  x_{1}^{y}

Double Scripting
Note that you can not double subscript or double superscript with out enclosing the first level in braces. For example, the input
	$latex x_1_2 $$
would generate an error message. On the other hand the input
	$latex {x_1}_2 $$
would result in the output  \[

OMhelp's Latex groups sequences of letters as a single input token. In addition, Latex numbers are multiple characters and grouped as a single token. For this reason, the input
	$latex x_ab  x_12  x_ab12 $$
will generate the output  \[
     x_ab x_12 x_ab12
Standard Latex, as per Lamport's reference , would output  \[
     x_a b x_1 2 x_a b12
for this input. It may be that future versions of OMhelp will adopt this convention. Thus, if you wish to group more than one character in a subscript or superscript, you should use parenthesis. For example, the following input would obtain the same effect as the input above:
	$latex x_{ab}  x_{12}  x_{ab} 12 $$
