[Ipopt] Variable-Mapping Gams <-> Ipopt

i try to study the problem structure of a model coming from GAMS (via
GAMSlinks). For print_level >= 8 I get the ouput with the current x
values (curr_x[i]), the current c values (curr_c[j]).

How do I know which i in Ipopt corresponds to which variable in the GAMS
model and which j in Ipopt corresponds to which constraint in the GAMS

With kind regards,
Martin Schmidt
