Dear All,

please help me with my problem. i have quite a big program all parts of which are distributed in the several code edit regions and in the main text. i'd like to find all occurenses of gven text in all open documents including code edit regions. i know how to do it manually by openening each code edit regiong and pressing Ctrl-F. however it is very time consuming and defocuses me apart from my main tasks. i'd prefer to use some combinations of 'hot keys' on the keybord or one or two mouse clicks as for example in MS Visual Studio.  

Good day! Some of my tasks are quite time consuming. What maple command I have to use in order to get some sound signal when calculation is over?

by trying to solve the following system of equations:

sys := {V[0]*(diff(P[0](t), t))/(k[B]*T0) = -z*C*A[1]*P[0](t)*(P[1](t)/P[0](t))^(1/gamma)*sqrt(2*gamma*(1-(P[1](t)/P[0](t))^((gamma-1)/gamma))/((gamma-1)*k[B]*T0*m0)), V[1]*(diff(P[1](t), t))/(k[B]*mu[T][1](t)) = z*C*A[1]*P[0](t)*(P[1](t)/P[0](t))^(1/gamma)*sqrt(2*gamma*(1-(P[1](t)/P[0](t))^((gamma-1)/gamma))/((gamma-1)*k[B]*T0*m0))-C*A[2]*P[1](t)*(P[2](t)/P[1](t))^(1/gamma)*sqrt(2*gamma*(1-(P[2](t)/P[1](t))^((gamma-1)/gamma))/((gamma-1)*k[B...

please give me advise how can i find some text fragment in Math 2D mode?

I tried to solve the system of odinary differential equations. But system was not able to solve it. As a result i've obtained a error message displayed on the last line of my program. Give me advise please how to overcome this problem.
