Initializing help system before first use

getobjintattr, getobjdblattr

Purpose
Retrieves the value of an Optimizer attribute associated with a multi-objective solve. When solving a multi-objective problem, several objectives might be optimized in sequence. After each solve, the problem attributes are captured so that they can be queried afterwards.
Synopsis
function getobjintattr(solveidx: integer, attrname: string): integer
function getobjrealattr(solveidx: integer, attrname: string): real
Arguments
solveidx 
Index of the solve to query. Must be between 1 and XPRS_SOLVEDOBJS.
attrname 
Name of the attribute to query.
Example
Query the number of MIP nodes created during the first iteration of a multi-objective solve: 
nodes := getobjintattr(1, "XPRS_nodes")
Further information
See the Xpress Optimizer Reference Manual for more information about multi-objective optimization.
