After your corrections, I noticed there is a comma where there should be a semicolon, also there are spaces around the semicolons. I do not know if they are there in reality, I adjusted FS to compensate. If they are not there you can just use ";". Please put more care still into your file sample specifications.

Try:

Code:

awk '
  BEGIN {
    FS=" *; *" 
    OFS=";"
  } 
  FNR==1{
    c++
  }
  c==1 { 
    A[$1]=$0 
  } 
  c==2 { 
    A[$2]=A[$2] OFS $1
  }
  c==3 { 
    $1=A[$1]
    print
  }
