I just upgraded servers, and I'm now on 'perl v5.8.8 built for i386-linux-thread-multi' and a simple log script doesn't work. I got it changed to
Code:
#!/usr/bin/perl
use strict;
[code]....
This is my sub;
Code:
sub projName
{
print "Enter project name: " ;
$PROJ = <STDIN>;
print "";
[code]....
I can call this routine and it works fine when I enter a valid name for $PROJ. If I enter an invalid name it goes to the else block and prints the statement. However, it does not call itself. Instead the script just exits.I've googled 'perl recursive subroutines' and the example don't appear to be doing anything different.
i am trying to do something very simple like a header and a footer for my first perl programs, what iam trying to do is that when i create a file in vim: lets say hello.pl , i would like that file to have already this in its header:
#!/usr/bin/perl
and this on the footer:
print "
";
so that i dont have to type everytime #!/usr etc i tried to do it this way but i get weird vim errors: header is a file that contains the header and footer $ vim hello.pl;header > is there another way to do it as a function in bash or some other one liner command?

I've been requested to modify a perl backup script we use which mounts a networked NAS machine. The actual mount command is called inside a system() command. In testing, I can do a test of the return value, so I'm able to tell whether or not I've mounted properly, but I can't make heads or tails out of the return on deliberate errors. (Such as mounting a non-existent box.) I'm displaying the returned value, which is 256 in my tests. The man page for mount listed error messages with values from 1 to 64, but no higher. Am I drawing this error value from the system command somehow? And what would be the best way to determine what this error means?

I am passing an array in function. I want to read the first content again and again until it is empty so
function calltoarray

read $1[0]
while [ ! -n "$1[0]" ]

But the code is not working. If we just press enter without value at read $1[0]. It do not get into while loop.
I am piecing a Mandelbrot generator up, I have one working to produce a 1,500 x 1,500 picture (which is fairly accurate).
I would like to increase the resolution over 100,000 x 100,000 + (into the millions x millions).
How I can achieve this? What kind of buffer sizes do I need?
(note this code doesnt have any memory allocations yet)
Here is my code so far:

It has working "def sav_scr_vars" and "def AddEntry" but these save to a fixed filename when save as defults or ok button is clicked. This is fine but I want to be able to save via the same proccess to a named ~/bin/settings/xxx.set file what I did is clone the to above def's and try to edit them I got the "read file" to work fine from a saved file in this manner. but I can't seem to get the save to filename to work without errors. The cloned def's are "save_as" and inmain.py "write_config2"
the camm2.defaults file goes in ~/.hpgl
copy and paste this to ~/.hpgl/camm2.conf

The file is always to have a .set extension and only read and write to ~/bin/settings

im trying to build a simple program for my C programming class, this is the source code
#include <stdio.h>
int main()
{
int length, width, length, height, area, perimeter;
perimeter = width + length + height;
area = width * length + heigth;
[Code]...
i dont see any error (you might)but every time i run it it runs but after it asks me to input for the width i do it but it doesn't take me to the length, it just stays blank until i input another value in the same place for the width, it asks me for 4 inputs in total i don;t know why, and after i run it different times it gives me different values for the perimeter and are. how can I fix this?

View 2 Replies View RelatedTrying to learn python. Going well, but I have run into a minor speed bump. I wrote a simple program to see if Python was set up correctly. Wouldn't you know it, the thing pops open and then closes again. I put raw input fields there to stop the program, but they didn't work. The program is:
Code:
x = raw_input("Please input your name: ")
print "Hello " + x + ". Good to meet you."
raw_input("Press Enter to exit")
And as for python, I have installed the following packages. The program was made in IDLE using Python2.6 I just started learning python a few days ago, so this may be a really small mistake.
