[_DONTWAIT](_DONTWAIT) is used with the [SHELL](SHELL) statement in **QB64** to specify that the program shouldn't wait until the external command/program is finished (which it otherwise does by default).
|
|
|
|
## Syntax
|
|
|
|
> [SHELL](SHELL) [_DONTWAIT] [commandLine$]
|
|
|
|
## Description
|
|
|
|
*Runs the command/program specified in commandline$ and lets the calling program continue at the same time in its current screen format.
|
|
*Especially useful when CMD /C or START is used in a SHELL command line to run another program.
|
|
* **QB64** automatically uses CMD /C or COMMAND /C when using SHELL.
|
|
* **QB64** program screens will not get distorted or minimized like QBasic fullscreen modes would.
|
|
|
|
## Example(s)
|
|
|
|
```vb
|
|
|
|
SHELL _DONTWAIT "notepad " + filename$
|
|
|
|
FOR x = 1 TO 5
|
|
_LIMIT 1
|
|
PRINT x
|
|
NEXT
|
|
|
|
```
|
|
|
|
(opens up notepad at the same time as counting to 5)
