Whoa! Don't open the Perl interpreter. At the c:\perl prompt, type perl hello.pl. Type set. If c:\perl is in the search path, you can type "perl hello.pl" from any location in the directory tree. If its not in the search path, you can add Perl to the search path. Either edit the existing path statement, or add one below it with like this: PATH=%PATH%;C:\perl in the autoexec.bat. Viola!

Re: MS-DOS
Is Perl in your system path? The first line in the script doesn't help any in DOSneyland. I usually just type "perl script.pl" if it is. It is possible to associated the dot-p-l extension with Perl.exe in the Windows GUI, but I don't believe its possible to flag an executable in dos that isn't EXE or COM (or BAT or CMD).

Re: how can system() execute all .exe file?
Are you specifying the full file path? Are you using UNIX-style forward
slashes for directory delimiters?
Perl on NT will follow Windows conventions about finding and executing
files, and I never rely on the search path. Its always better to give a
full path to the executable.
Ex.
#!/usr/bin/perl -w
# Running an exe in DOSneyland with full path & 'Nixian slashes
use Strict;
use Diagnostics;
system ("e:/ntreskit/ls.exe -l e:/eric");

Re: rant on space
Consider this a formal request that the list messages should default to reply to the list, and either copy the originator (or no one). This would best accomodate the way people communicate on lists, in my view. I didn't originate this thread, but I feel compelled to comment in that I typically use a list client that is not configurable to accomodate this. I also find that this behhavoir is different that that of most of the lists I have followed via this account. TIA = - Notice: This e-mail is protected by the U.S. Constitution and the U.N.

Not sure why perl.exe wouldn't run it without an absolute path, but
such are the ways of DOSneyland.

Re: A gentle reminder about jeopardy quoting
But we should be encouraging the list members to avail themselves of the Perl FAQ and all the other resources at their disposal. I know I always want to exhaust as many other avenues as possible before admitting to thousands of stranges that I can't figure it out. But that's just me. Many of us learned our on-line etiquette the hard way, in less gentle forms at a time when the Internet was first catching fire in the 90s. (Remember when AOL.COM = flamebait?). If there was a welcome to the list e-mail other than the bot instructions, I don't remember it and didn't save it like I usually do listadmin stuff. Perhaps a gentle introduction to the list to new subscribers would be sufficient, with off-line/direct mail nudging of folks (so we dont' clutter up the list like I'm doing now) with meta-matter. --- Elaine -HFB- Ashton <[EMAIL PROTECTED]> wrote: > *>I think gentle etiquette reminders are fine, if they don't begin to > bog > *>down the list.

RE: A good book?
I have moved more onto to the Programming Perl level of interest. However, next time I'm in the bookstore I will have a look at _Beginning Perl_, as I'm always on the lookup for ways to help my fellow travelers. I am not wedded to O'Reilly, even though I have quite a managerie between work and home. And, for what many of us do, Mastering Regular Expressions should be boarded onto the ark fairly early. (I have bookmarked the on-line as yet unpublished tome mentioned in other threads, but have not had time to look at it).

RE: A good book?
I also backed into programming. I am the quintessential "Just Another English Major Turned SysAdmin" sort. I also came in from DOSneyland and not from UNIX. Still, I only undertook to learn Perl after some poking around to see what language would allow me to best do the sort of automations I wanted to do. Later, when I found myself deep into list processing to condition bad customer data files, I was glad I chose Perl. Learning Perl may not teach you OOP, but that was not what a true beginner comes to learn. I thought it excellent and occasionally entertaining. (I still chuckle when I think of the index entry for RINDEX). In general, for someone of my sort, Learning Perl is clearly the way to go. Having gotten through that, one should then rush out and acquire Programming Perl, and read the first several chapters carefully. Someone approaching Perl with a much stronger programming background might prefer to tackle Programming Perl or another book directly. I am not sure, however, that an experiened C++ program is the intended audience of this list. Then subscribe to this excellent list, and get down to work. --- Chris Lott <[EMAIL PROTECTED]> wrote: > Chris> Personally, I think _Learning Perl_ is really showing its age. > > I'm going to try to figure out how to say this without insulting a > book that > I *do* like and authors who are both Perl wizards and whose writing > has > given me a lot.
