dump local error

hi,
i am getting an error in running following code(dump local)


compute 1 all property/local batom1 batom2 btype
dump 1 all local 1000 tmp.dump index c_1
ERROR: Dump local compute does not calculate local vector


In lammps manual eg: is given as follows

compute 1 all property/local batom1 batom2 btype
compute 2 all bond/local dist eng
dump 1 all local 1000 tmp.dump index c_11 c_12
(c_11 c_12 i just wonder why 1 and 2 are bold ) |

The c_11 is a typo in the HTML formatting for the doc page - it should read c_1[1], etc.
I just changed it.
