by v_vorn / January 3, 2010 5:23 AM PST

when you double click in tc.exe ,16 bit MS-DOS Subsystem and said"This system does not support fullscreen mode.Choose 'Close' to terminate the application.

Solution that i found as below:

1> you have to download DOSBox 0.73 following's shown:

2>after download and intalled it,you go to start>program>DOSBox-0.73>configuration>Edit configuration,now you'll see the notepad>then goto lastest below of this file>until u see [autoexec],under this line type:

mount c c:\ ,then Save it.

3>now goto DOSBox-0.73 in desktop icon or somewhere. then 'll see

z:\>mount c c:\
Mounting c:\ is NOT recommended .Please mount a(sub) directory next time.
Drive c is mounted as local directory c:\
then type in command as below then enter( step by step)
c:\>cd tc
c:\TC>cd bin

it's actually successful working...
I'm using Aspire 5738 with windows 7.

one thing,about issues 'can't read stdio.h and conio.h ' it's sloved already now,just certainly check the directory...wish any one got the points as me quickly...

see any one had shared ideas about it ,goto >>>

thanks you!!!!

All the best,

Let's try this. Dosbox is a fine idea but why not run DOS in VIRTUAL BOX ? (see google.)

The can't find a file issue could be the translation getting lost from NTFS to/from 8.3 file names. But you could figure that out fast.

Vista will allow Qbasic in full screen mode under Admin, System 7 will not. Now I can finish learning Sprites & DirectX10 in VB2008 without testing my Mathematica formulas on paper. THx ^__^ DOSbox is a life saver. traxx

Still not working with dosbox.
by viresh284 / September 20, 2010 4:57 PM PDT


I tried this solution, but still facing some issue.
Dosbox opens in full screen, but the actual screen where we edit
and see output is of same size. What has happened is size of editable
area is still the same, just black background is shown in rest of the screen.

Is somebody else facing similar issue.
