IE 640x480 + IE8 + perl

Version PASPAD-459 has a great option:
IE 640x480
IE 800x600
etc.

Is not there a bit of its complement:
IE-11
IE-8
Chrome-42
FireFox
etc.

So supplement:
While viewing a show not only the processed HTML, CSS, Javascript and Perl scripts, for example: print "AskMe";

There is necessary to restart application after you change IE compatibility (PSPad program settings / System integration) - Windows limit.
To display content in Chrome or FF you need to include their engine - you can't use browsers directly. In the past there were MozillaX Control (obsolete now), there is an Chromium SDK (about 200MB).
You can use external application (Highlighter settings / HTML) to open your web page in different browsers - it's simplest way how to do it.

1.IE, FF, Ch, Perhaps it is unreasonably difficult.

2.But it would be very useful to have one editor and launch Perl programs, such as in DzSoft.

3.In any case, PSPAD very good! An enormous thank you!

I don't know DZSoft, but PSPad offers you to assign any compiler for any language. Look into help for compiler examples. There you will find how to setup Perl in PSpad, it will allows you compile, run e.t.c. Perl programs directly from the PSPad.
