I want to thank everybody for your help/support.
Many have suggested that I upload the program for test.
Problem is that it is a very long program with references to files in different drives on my computer.
So I've created this test program.
Here's one way to do it. I'm not aware of a way to draw on a screen that's not displayed, though on my machine, I don't even notice a flicker when it starts up. I ran this on Linux, but everything here should be cross platform.
include std/graphics.e cursor(NO_CURSOR) sequence screen = {0, 0} -- set up the screens clear_screen() text_color(GREEN) bk_color(WHITE) puts(1, "\nThis is page 0\n") text_color(BRIGHT_WHITE) bk_color(BLACK) puts(1,"Hit any key\n") screen[1] = save_text_image( {1,1}, {80, 25}) clear_screen() text_color(WHITE) bk_color(GREEN) puts(1, "\nThis is page 1\n") text_color(BRIGHT_WHITE) bk_color(BLACK) puts(1,"Hit any key\n") screen[2] = save_text_image( {1,1}, {80, 25}) integer active_screen = 1 while 1 do clear_screen() display_text_image( {1,1}, screen[active_screen] ) wait_key() active_screen = 3 - active_screen end while
