[Symphony] solution export and var names

[Joost]

Dear,
 
I have the same questions as Paulo Gouveia (see post nov. 18th).
My setup is using zimpl in combination with Symphony (interactive)
environment (LP files).
 
- The 8 char truncated variable names are unpractical from a user point
of view using the above setup.
It would already help a lot if this could be increased to 64 chars or so
(I think Cplex limit is 255).
 
In the source I made a couple of changes to the length of the column
names:
 
int read_lp(MIPdesc *mip, char *infile, char *probname) [lp_solver.c]
int receive_lp_data_u(lp_prob *p) [lp_wrapper.c]
int send_lp_data_u(sym_environment *env, int sender) [master_wrapper.c]
int display_solution_u(sym_environment *env, int thread_num)
[master_wrapper.c, around line 720]
 
It seems to work, but I'm unsure whether this is a correct and safe way
to do it.
 
- It would be nice to have a command to export the solution to a
textfile after solving.
 
- Another nice to have would be a pre-compiled binary of 5.4.x in the
binary section (5.2 is lastest version present).
 
Best regards,
Joost
