Oops, not quite right because it inserts colons blindly in the first field -
which appears not what you want. More correct implementation in Python:
!/usr/bin/env python
import sys
for line in sys.stdin.readlines():
line = line.strip().split()
label = line[0]
comment = " ".join(line[3:])
print("%s DC %s+2 %s" %(label, label.replace(':', ''), comment))
