5.10 6.00 6.00a 6.00ax 7.00 | 5.10 6.00 6.00a | 1.00 1.50 MS-DOS | OS/2 | WINDOWS kbprg ---------------------------------------------------------------------- The information in this article applies to: - The C Run-time (CRT), included with: - Microsoft C for MS-DOS, versions 5.1, 6.0, 6.0a, and 6.0ax - Microsoft C for OS/2, versions 5.1, 6.0, and 6.0a - Microsoft C/C++ for MS-DOS, version 7.0 - Microsoft Visual C++ for Windows, version 1.0 and 1.5 ---------------------------------------------------------------------- When using the Hercules graphics adapter in graphics mode, each pixel maps to only 1 bit in memory. Because there is only 1 bit, that pixel can only be on or off. In Hercules graphics mode, there is no facility for attributes such as high-intensity, blinking, reverse, or underline. In Hercules graphics mode, to obtain blinking, reverse, and underline, your program must manipulate or turn on and off each pixel. High- intensity is not possible. If you put the adapter into Text mode, you can use all of these attributes freely.
