Initializing help system before first use

problem.writeslxsol

Purpose
Creates an ASCII solution file ( .slx) using a similar format to MPS files. These files can be read back into the Optimizer using the problem.readslxsol function.
Synopsis
problem.writeslxsol(filename, flags)
Arguments
filename 
A string of up to 200 characters containing the file name to which the solution is to be written. If omitted, the default problem_name is used with a .slx extension.
flags 
(optional) Flags to pass to writeslxsol:
l 
write the LP solution in case of a MIP problem;
m 
write the MIP solution;
p 
use full precision for numerical values;
x 
use hexadecimal format to write values;
d 
LP solution only: including dual variables;
s 
LP solution only: including slack variables;
r 
LP solution only: including reduced cost.
Example 
p.writeslxsol("lpsolution", "")
This saves the MIP solution if the problem contains MIP entities, or otherwise saves the LP(barrier in case of quadratic problems) solution of the problem.
