@BrowserUK . Plz elaborate how can tell the script A to suspend through script B(I cannot hardcode in script B to suspend for some time as that would be known only at runtime)and then resume again?

    Given count.pl that looks like this:

    C:\test>type count.pl #! perl -slw use strict; use 5.010; say for 1 .. 1e6;

    You can run that script using this script:

    #! perl -slw use strict; use Win32::Process; Win32::Process::Create( my $hProc, '/perl64/bin/perl.exe', 'perl count.pl', 0, 0, '.' ) or die $^E; my $state = 1; while( <STDIN> ) { if( $state ) { $hProc->Suspend(); $state = 0; } else { $hProc->Resume(); $state = 1; } print "\nProcess is ", $state ? 'running' : 'suspended'; }

    And each time you press enter on the command line, count.pl will be suspended or resumed.

    In the absence of evidence, opinion is indistinguishable from prejudice.

      But again it keeps on waiting for some input from user as the process does not finish. It cmd running the process keeps on waiting. Why?
