E.g. this is more useful in telling what is wrong:</p> <pre> dsolve(diff(f(x),x)=0,x,x=-1..1); Error, (in ODEtools/info) found wrong extra arguments: {x, x = -1 .. 1} <p>&nbsp;</p></pre> The latest comments added to the Post, make error message more useful 61180 Mon, 07 Dec 2009 20:44:54 Z jakubi jakubi http://www.mapleprimes.com/posts/36201-Make-Error-Message-More-Useful?ref=Feed:MaplePrimes:make error message more useful:Comments#comment61181 <p>and sometimes the message is obscure -- what is a &quot;typed procedure&quot;?</p> <pre> f := x-&gt; x^2: fsolve(f=0,x,x=-1..1); Error, (in fsolve) Can't handle expressions with typed procedures </pre> The latest comments added to the Post, make error message more useful 61181 Wed, 09 Dec 2009 10:20:37 Z PatrickT PatrickT http://www.mapleprimes.com/posts/36201-Make-Error-Message-More-Useful?ref=Feed:MaplePrimes:make error message more useful:Comments#comment61182 <p>When I posted my initial message, here's what I got, I think: <br> <br /> <br /> <br /> </br><br /> solve(f=0,x,x=-1..1);<br /> Error, (in solve) invalid arguments</p> <p>But when I ran the code again today, here's what I got instead:</p> <p>solve(f=0,x,x=-1..1);<br /> Error, invalid input: too many and/or wrong type of arguments passed to solve; first unused argument is x = -1 .. 1</p> <p>Has Maple been updated overnight? Had I drunk too much maple syrup?</p> <p>I most likely ran the first call in the middle of another session, but other than that I can't think of why this discrepancy came up. The second error message is a lot more useful, similar to the one jakubi posted above with dsolve.<br /> &nbsp;</p> The latest comments added to the Post, make error message more useful 61182 Wed, 09 Dec 2009 10:24:45 Z PatrickT PatrickT
