Initializing help system before first use

OUTPUTLOG

Description
This controls the level of output produced by the Optimizer during optimization. Output is sent to the screen ( stdout) by default, but may be intercepted by a user function using the user output callback; see XPRSaddcbmessage. However, under Windows, no output from the Optimizer DLL is sent to the screen. The user must define a callback function and print messages to the screen them self if they wish output to be displayed.
