_SHELLHIDE

The _SHELLHIDE function hides the console window and returns any INTEGER code sent when a program exits.

returnCode% = _SHELLHIDE(externalCommand$)

• The literal or variable STRING externalCommand$ parameter can be any external command or call to another program.

• A QB64 program can return codes specified after END or SYSTEM calls.
• The returnCode% is usually 0 when the external program ends with no errors.

Shelling to another QB64 program will return the exit code when one is set in the program that is run.

returncode% = _SHELLHIDE("DesktopSize") 'replace call with your program EXE

PRINT returncode%

END 

Explanation: To set a program exit code use an INTEGER parameter value after END or SYSTEM in the called program.
