Is there a way to override LaTeX's errors about double subscripts and superscripts?

Minor point about LaTeX that bothers me. When one writes 

a^b^c, a_b_c

or 

a'^b

in math mode, LaTeX gives an error message complaining about multiple super/subscripts. This is particularly annoying after replacing a string containing a super/subscript or when using the apostrophe, '.

Is there a way to override the error and have LaTeX simply output 

a^{bc} a_{bc} {a'}^b

and so on?

Solution

  • The following is what you wish

    \catcode`\^ = 13 \def^#1{\sp{#1}{}}
\catcode`\_ = 13 \def_#1{\sb{#1}{}}
