A detailed description of the format of the RC files used by MAKEINI is included in the book OS/2 2.11 Power Techniques. (see also Predefined Object IDs)
Note: see Get the default object settings for an example for parsing an RC file.
Note: In OS/2 WARP, the UPDATE and REPLACE flags in the setup strings of some of the entries in the INI.RC have no effect on the options in the object's pop-up menu of existing objects. To get around this limitation, use SysSetObjectData to change the object properties (Source: APAR PJ18673).
