Hello

I think there is no  C function available to do so, but it is quite easy
to write:

The varaiable names are stored in the integer array named idstk located
in the C structure named C2F(vstk) . If k is the variable index the name
is stored in C2F(vstk).idstk[k * nsiz]) to C2F(vstk).idstk[(k+1) *
nsiz-1]) where nsiz=6;
in a coded way. To decode it on can use the C2F(cvname) function:
 C2F(cvname)(C2F(vstk).idstk[k * nsiz]) ,str,(int job=1,&job))
The valid values for the index k are in the interval
[C2F(vstk).bot-1,C2F(vstk).isiz-1] for the regular variables and in
[C2F(vstk).gtop-1,C2F(vstk).gbot-1] for the global ones.
