Graphics Function: Returns the current graphics color index.
USE IFQWIN
result = GETCOLOR( )
The result type is INTEGER(2). The result is the current color index, if successful; otherwise, -1.
GETCOLOR returns the current color index used for graphics over the background color as set with SETCOLOR. The background color index is set with SETBKCOLOR and returned with GETBKCOLOR. The color index of text over the background color is set with SETTEXTCOLOR and returned with GETTEXTCOLOR. These non-RGB color functions use color indexes, not true color values, and limit the user to colors in the palette, at most 256. For access to all system colors, use SETCOLORRGB, SETBKCOLORRGB, and SETTEXTCOLORRGB.
