SHELL observation

[Timbergetter]

If I run the following 5 commands I get a directory list on the output screen as expected:

Code: QB64: [Select]

1.    OPEN "runme.bat" FOR OUTPUT AS #1
2.    PRINT #1, "dir"
3.    PRINT #1, "pause"
4.    CLOSE
5.    SHELL "runme"

However if I run:

Code: QB64: [Select]

1.    SHELL “dir”

by itself I see the directory listing for a few milliseconds and then a blank output screen.

In QuickBasic 4.5 the SHELL “dir” command does produce a directory listing to the output screen and it remains there.

I am keen to know how to interpret what I am seeing here.

Code: QB64: [Select]

1. $CONSOLE
2. SHELL "dir"
3.

Thank you Pete, that’s great feedback.  I see now the added flexibility of the console commands.  So am I right in thinking that shelling to an internal dos command (dir) activates the console but then issues a  _CONSOLE OFF by default?  Whereas shelling to a dos batch command activates the console and leaves  _CONSOLE ON by default.

You may be right
I may be crazy...

Code: QB64: [Select]

1. $CONSOLE
2. _SCREENHIDE
3. SHELL "start dir"
4. SYSTEM

Using START will leave the console open when the QB64 window, hidden with _SCREENHIDE, closes.

What timing!
I had just now the same problem...

At QB, it seems to me that the management of the SHELL was different. Maybe it was simpler and more direct.
