#pragma disable_warning number
#pragma enable_warning number
Controls the compiler's printing of individual warning messages. Warning
messages generally indicate a problem in the model file, or a place where the
code could be improved. Warning messages are on by default. These
pragmas can be intermixed multiple times throughout a model file to turn
informational message printing on and off as needed.
The number parameter refers to a specific warning number, for example
#pragma disable_warning 123. Alternatively, you can use an asterisk to
select all warnings, for example #pragma enable_warning *. This pragma is
ignored if you specify #pragma warnings_off or #pragma fyi_off.
