_DONTWAIT is used with the SHELL statement to specify that the program shouldn't wait until the SHELLed command/program is finished (which it otherwise does by default).


Syntax:

SHELL [_DONTWAIT] [commandline$]


Description:

  • Can only be used in the SHELL statement when using QB64.
  • Runs the command/program specified in commandline$ and lets the calling program continue at the same time in it's 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 could.


Code Examples:

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)

1 2 3 4 5
