; This file shows how to solve an equation for an unknown variable.

; Solve f(x) = x^3 - 2*x - 5 .

!solve x, [-100,0]: x^3 - 2*x - 5 ;please wait, this takes a few seconds!

; We did not find a solution in the interval -100 to 0. When this happens

; either there is no solution in the interval or the search interval is

; too large or includes singularity points.

!solve x, [0,100]: x^3 - 2*x - 5

; Here we did find a solution in the interval 0 to +100. The solution is

; stored in the variable 'x' after the solve command completes.

Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
