The _DEFAULTCOLOR function returns the current default text color for an image handle or page.
Syntax
- result& = _DEFAULTCOLOR [(imageHandle&)]
Description
- If imageHandle& is omitted, it is assumed to be the current write page or image designated by _DEST.
- If imageHandle& is an invalid handle, an invalid handle error occurs. Check handle values first. Zero designates the current screen.
- Default foreground colors are: SCREEN 0 = 7, SCREEN 1 and 10 = 3, SCREEN 2 and 11 = 1. All other SCREENs = 15.
