dmmiller2k is right.
You also want to be sure that the 'text' that you are reading is examined as a single string, by your matching pattern (not one line at a time).
Then the regex is pretty simple (but note the /s operator is added, as dmmiller2k advised).
#!/usr/bin/perl -w
use strict;
#examine DATA as a single string.
$/ = '';
while (<DATA>){
#'.' will match \n with the /s operator
if ( m/if.+else/s ){
s/{//;
s/}//;
}
print;
}
__END__
if (c=e)
{ #// delete this curly brace
call pgme;
call pgmd;
}
else
{
call pgmd; #// keep these curly braces
call pgmc;
}
if (c=e)
{ #// delete this curly brace
call pgme;
call pgmd;
}
else
{
call pgmd; #// keep these curly braces
call pgmc;
}

update please note that this regex example is
for illustration only - it's easily broken and the reason
it appears to work is because of the structure of the data example.

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).
