Ctrl+z normally generates a SIGTSTP on Unix so
if $^O is Unix based, you should be able to use:
{
# code block you don't want to be interrupted
local $SIG{TSTP} = 'IGNORE';
local $SIG{INT} = 'IGNORE';
...
}
# resume code that is ok to interrupt
[ You could also set both signals at once:
local @SIG{INT,TSTP} = ('IGNORE') x 2; ]
On the other hand if $^O is Win32 based, you
probably want to take a look at Win32::API.
