in reply to Waiting For Input

Temp.pl script runs and completes execution and then keeps on waiting ie does not end. Why?

Because it is written that way. Maybe its waiting for input, like pause, or something else entirely, depends on what temp.pl does

The cmd cursor keeps blinking even after the Temp.pl script is run

cursors are designed to blink, its what they do

    No Temp.pl does not need any input nor any pause. Rather the main scipt conatins this:

    use Win32::Process; use Win32; sub ErrorReport{ print Win32::FormatMessage( Win32::GetLastError() ); } Win32::Process::Create($ProcessObj, "C:\\Perl\\bin\\perl.exe", "perl Temp.pl", 0, NORMAL_PRIORITY_CLASS, ".")|| die ErrorReport(); $state = 1; while( <STDIN> ) { if( $state ) { $$ProcessObj->Suspend(); $state = 0; } else { $$ProcessObj->Resume(); $state = 1; } }

    How do i end both the scripts? i think it is the main script that keeps on waiting..

      So, when does the loop end?

      while( <STDIN> ) { ... }

      Maybe you want to print out some diagnostics at the end of Temp.pl and in your main script, to learn when a program starts or finishes, and when a program waits for input.

        The Temp.pl script gives me the last print statement conatined in it . So I know that the Temp.pl ends, But How do i tell this while loop to end? <\p>
