Re: Converting multiple lines into single line.

On the other hand, if you insist on reading a line-at-a-time, let's just define lines to end on a '}';

#!/usr/bin/perl

# http://perlmonks.org/?node_id=1206966

use strict;
use warnings;

local $/ = '}';

while(<DATA>)
  {
  s/^war \V* \K \{ .* \}/ $& =~ tr|&\n||dr /emsx;
  print;
  }

__DATA__
some starting text
war eligible, init =0*DEC0, ev (VARIABLE){1*BIN0,2*DEC3,6*BIN4,
& 5*BIN43,6*DEC32,
& 5*BIN43,7*DEC32}
some other text
war wear, init =1*DEC1, ev (VARIABLE) {
& 1*BIN0,2*DEC3,6*BIN4,
& 5*BIN43,6*DEC32,
& 5*BIN43,7*DEC32,6*DEC32,6*DEC3,
& 8*BIN3,6*DEC34
}
some final text

Outputs:

some starting text

+3,6*DEC32, 5*BIN43,7*DEC32}
