getline produces an illegal output and causes an error

[cyberman]

Hello

i have some problems with getline under Matrixx 7.17 - windows xp

Calling getline und typing something into the line produces an output like:

plot2d_cb "on_click_border", "MainWin",3;

plot2d_cb "on_click_border", "MainWin",3;

The input of the user is ignored.

This problem only occures when getline is  used in a function together with plot2d.

Is this problem known? What can i do to fix this bug?

i just build an example to document the problem:

Execute getlinetest.ms

File getlinetest.ms

================

erase {logarea}
display("This Script will show the problems with getline and plot2d")
display("plot2d seems to send his output to getline....")
pause ""
out=getlinetest_in_function(2)

File getlinetest_in_function.msf

==========================

function out=getlinetest_in_function(def_zahl)

plot_win_ampsec2=34

y2=[cos(time_vek),1+cos(time_vek)]
y3=[cos(time_vek),sin(time_vek)]

Hi Ralph,


We have duplicated your problem in 7.1.8. It does work in 8.0 though.

We might be able to fix it in a later 7.1.x release but I cannot commit to a date on that yet.

Hi Dirk

thank you for your answer.

Can you give me a hint to get an alternativ to getline?

An upgrade to 8.0 is not possible at this time, because i would have to check more than 600 programs and i dont have the time for this now.

If there would be a workarround for getline this would solve  my problems for the moment.,

Ralph
