### Function 113h - Remarks

There are two types of code page sets. The first code page set allows a code page to be set while the mode of the display (as used by Function 10Dh ) remains the same. The other type of code page set causes a change in the display mode. This occurs when switching between DBCS and non-DBCS code pages.

If bit 6 of the flags WORD is set and bit 7 is clear, the code page is set when the adapter can use the code page without changing from DBCS mode to SBCS mode, or vice versa. The mode should be changed if both bits 6 and 7 of the flags WORD are set, and the code page is used when the mode is changed from SBCS mode to DBCS mode. Bit 7 is ignored if bit 6 is not set. This applies only to text modes. Graphics modes are not set to text modes by forcing a code page.

The BVH need not support any scrollable region other than the entire display area. The adapter may support any scrollable rectangle up to the size of the entire screen. All coordinates are in text display cells. This scrollable rectangle data is undefined for graphics modes.
