SUMMARY
It is sometimes desirable to randomly generate colors, for example, for a screen that changes the color for a @ ... SAY statement. This article demonstrates a sample procedure for creating random colors.

MORE INFORMATION
The following code displays the text "This is a test" with various randomly generated colors.

FOR i = 1 to 50 colorpair = randcolor @ 2,2 SAY "This is a test" COLOR &colorpair FOR n = 1 to 10000 && Slows it down a bit so you can see it! ENDFOR ENDFOR

PROCEDURE randcolor numcolor = INT(RAND*100)                && Create a 2-digit number num1 = ALLTRIM(STR(numcolor/10))          && store 1st digit num2 = ALLTRIM(STR(INT(MOD(numcolor,10)))) && store 2nd digit * Select one valid color from random digit color1 = CHRTRAN(num1,"0123456789","WNRGBBGRNW") color2 = CHRTRAN(num2,"0123456789","WNRGBBGRNW") * Combine two colors to create color pair colstrg = color1 + "," + color2 RETURN colstrg Additional reference words: VFoxWin 3.00 FoxMac FoxDos FoxWin 1.02 2.00 2.50 2.50a 2.50b 2.50c 2.60 2.60a KBCategory: KBSubcategory: FxprgGeneral Keywords         : kbcode FxprgGeneral Version          : 1.02 2.00 2.5x 2.6x | 2.5x 2.6x Platform         : MACINTOSH MS-DOS WINDOWS
