In order to get the names of variables in a list, you should use Names. Take a look at the following example: In[2]:= Names["t*"] Out[2]= {te, ts, t20a4p, t200a3p, t200a54p, t400a3p, t400a53p, t400a54p, > t400b53p, t400c54p, t500a53p, t500b54p, t500c54p, t550a53p, t550a54p, > t600a3p, t600a53p, t600a54p, t600b3p, t700a2p, t700a3p, t700a4p, > t700a53p, t700a54p, t800a2p, t800a3p, t800a4p, t800a53p, t800a54p} In[3]:= Names["t200*"] Out[3]= {t200a3p, t200a54p} If you want more information you might use: Map[ ToExpression[ "?"<>ToString[#] ] & , %3 ] Scan[ (ToExpression[ "??"<>ToString[#] ]; Print[" "]) & , Names["`*"] ] ... etc. Hope that helps !
