 Need Help??
Can you explain a few things I don't understand?

- First thing I don't understand is this way of making
subs (sub'i, sub'p, sub'f) what's the main difference
from the sub i{..}.

- Second, in this line : \;\$m.="\$/\$/\$/\$/\$/\$/1; I don't
really get what you are doing there.

- Third, \$/\$/\$/\$/\$/\$/\$/";; why ;;?

```#!/usr/bin/perl

\$m=q\\$g=59;
\$s=23;

@v=(\$",\$",'.',';','x','X','M');
\$t=[map{[(split('',\$_))[0..\$g]]}reverse+split(\$/,\$m)];

sub'i{
(\$b)=@_;
\$b->[0]=[(0)x(\$g+1)];

for(@{\$b->[0]}){
\$_=\$#v*(int(rand(7))<3);
}

for(1..(\$s)){
@{\$b}[\$_]=[(0)x(\$g+1)];
}
}
sub'p{
(\$b)=@_;
system(\$^O=~/MSWin32/ ? 'cls': 'clear');

\$str='';
for \$r(reverse(0..\$s)){
for \$c(0..\$g){
\$str.=(\$t->[\$r][\$c]eq\$"?\$":@v[int \$b->[\$r][\$c]]);
}\$str.=\$/;
}
print \$str;
}

sub'f{
(\$x)=@_;\$b=[];i(\$b);

for \$r(1..(\$s-1)){
for\$c(1..(\$g-1)){if(int(rand(2))){
\$v=0;for\$ri(-1..1){
for\$ci(-1..1){
\$v+=\$x->[\$r+\$ri][\$c+\$ci];
}
}

\$b->[\$r][\$c]=\$v/9;
}else{

\$b->[\$r][\$c]=\$x->[\$r-1][\$c];}}}
return \$b;

}

\$z=[];
i(\$z);
p(\$z);
while(1){
\$z=f(\$z);
p(\$z);
}

\;\$m.="\$/\$/\$/\$/\$/\$/1;
\$/\$/\$/\$/\$/\$/\$/";;
s//\$m/;
s/\$"//g;
s|\$/||g;
eval

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
