_DONTWAIT

_DONTWAIT is used with the 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 [_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)

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)
