spawn

SPAWN a child process (console or windows executable).

SPAWN Spawn a child process (DOS/WINDOWS)

rval = spawn('child process','arg1','arg2',. .'arg9');

child process - any executable
arg1 . . arg9 - arguments passed to the child process
rval - return value from child process

Description
SPAWN a child process (console or windows executable).

Use this in preference to the DOS() function if you need the return value from the child process. DOS() will always return 0 because it executes the child process via COMMAND.COM

COMMAND.COM returns 0 if it has finished succesfully regardless of the child process return value.
