1 to 20 with x number of 1's, 2's, 3's, ... 20's

This is probably a simple thing to do, so perhaps someone would send me in the right direction.

I need to generate a list containing numbers from 1 to 20, say. But I cant just use A = 1:20, for example, because that provides me only one instance of each of the values. What I need is X instances for each value. For example, 5 ones, twos, threes, and so forth.

Is there a simple command for this?

Regards,

Ulrik.

A bit vague.  You need to provide sample input(s) and output.

Python's __getattr__, Perl's autoload, Ruby's method_missing, and Smalltalk's #doesNotUnderstand
I'm still new here, and I just completed reading CLTL's documentation on packages and On Lisp's documentation on CLOS. It doesn't appear that Lisp has the equivalent of Python's __getattr__, Perl's autoload, Ruby's method_missing, and Smalltalk's #doesNotUnderstand. That is, there is no way I can do this (without new-function being defined): (new-function) and have it call some other function like this: (missing-symbol 'new-function) whose returning value will be evaluated as the value of new-function.

JSP, Servlet's, EJB's, Bean's?

What I would like to do is be able to call these programs. Using buttons or something, and dumping the output into a text area. I have a servlet that I generates the output that I need. My question is How do I get that output into the textarea? When I call a new function I want to be able to append the text to the end of the text area.

It's a Bird, it's a plane, no! umm, it's Super Boid?
Hey Guys, I have something actually working that seems allot like Swarm Technology to me. The system features many smaller parts that seem allot like "Boids" (or "Agents"). I'd be tempted to call them "Dorts" because they get thrown straight at the target and fire on my machine at about 2,000 per second (in 1.9). Not very "natural" - one would not want to have mosquitoes able to do that :) There's no "in-flight" communication between the Boids - their life cycle involves trying to attain values for a list of required attributes and a docking with a "HelperClass" (see Ruleby also) for any in-depth calculations. They make their assertions, record all the results, and wait to be debriefed after they have landed. So are these things Boids or not? For example: They are fired sequentially so they are not buzzing around sending signals to each other. However, if a Boid is assigned a lower pass number it can "leave information" for a Boids fired on later passes - so there is inter_boidal_communications :) - but only after their "flight" / period of activity. It's taken me almost 3 years to get this all this far along Right now, however, I can go on localhost and author 10 new real almost guaranteed to work "Boids" easily in an hour.(When I started and did these by hand they could take a full day.) Mostly all I have to do now is make multiple choices. (Lots of Ruby ...

What's the correllation between File I/O's and Disk I/O's
Hi We have a client that is getting poor response times. But it's not consistant. One person may have no problems one day while another is having huge delays, and the next day it's vice versa. The system we have does a lot of data entry. Depending on the data entered, a validation against files is required. We've done a lot of investigation into this, and one thing that we have noticed is that the number of Disk I/O's increases much faster than the File I/O's requested. One thing noticed was they had 9 disks, and disk 1 was going to 70-80% utilisation (WRKDSKSTS), which in turn caused the other 8 disks to increase in utilisation. The iSeries is not reporting damaged objects, files or access paths. Example File I/O's Disk I/O's Action 1: 155 127 Action 2: 230 478 Action 3: 285 400 Action 4: 340 377 Action 5: 420 1220 Action 6: 480 2720 Looking at the above example Actions 1-4 look OK to us (afte review the program source for Read/Writes and updates). But Actions 5 & 6 have much more Disk I/O than we'd expect. Should there be some sort of correllation between File I/O's and Disk I/O's? What governs Disk I/O is it the OS? Is there some configuration changes we might be able to make to help alleviate the problem? TIA John two things immediate. straspbal will balance the files by usage across disks more evenly some files are mostly found on...

seeing 1's and 0's
Dear all: Ok an learned about 1's and 0's and how to convert it decimal and back. But just wondering if it was possible to actually see the binaries in real life! In other words is it possible to actually open an executable and see all those 1's and 0's. From a geeky prespective, this would be kinda cool and a great way to learn this stuff! It would be kinda cool to change it lets say something that reads "google" to "googgle" by changing the binary itself. Any help would be greatly apprciated.

Prob's using Albert Kallal's SetDefaultPrinter on some OS's

I would like to overcome this and was wondering about the experiences of others who attempt to set default printer in A97? I have an app running on an XP home edition box fine. Same app running on XP Professional fails when SetDefaultPrinter() is called.

90's Game -- Spielberg's "Director's Chair"
This seems like a long shot (get it...long shot?) but is anybody reading this group familiar with a game called Steven Spielberg's Director's Chair from the mid-nineties? Actually, it's more of a movie- studio familiarizer than a game, per se, but it does have its strong points in terms of recreating a certain, Hollywood-y atmosphere. I'm curious because, when I run this program on a Windows 2000 box, I keep hitting an "Internal Error" during my first dip in The Lab. I can hear the first line of dialogue repeat about three times, then it shuts me down. Becau...
