Hi!

I have an ASCII file with the following data
....
C33
C34
C35 HE94-140 CDP 205 == SP 1001

C36 HE94-140 CDP 405 == SP 1101

C37
C38
C39
C40 CDPS 1 TO 9944 SPS 1001 TO 5873
...
the same with different values many times

What I want to extract is
HE94-140 1001 205 1 9944 (from C35 and C40)
HE94-140 1101 405 1 9944 (from C36 and C40)

What is the best thing to do?

Thanks for your help

 
Sort by date Sort by votes
awk '{
if ($6 == "SP") {
HE[NR]=$2;
CDP[NR]=$4;
SP[NR]=$7;
}
if ($2 == "CDPS")
for (i in HE)
if (SP>=$7 && SP<=$9 && CDP>=$3 && CDP<=$5)
OTH=$3 &quot; &quot; $5;
}
END {
for (i in HE)
print HE, SP, CDP, OTH;
}' file1

Or maybe

/^C35 /{a1=$2 &quot; &quot; $7 &quot; &quot; $4}
/^C36 /{a2=$2 &quot; &quot; $7 &quot; &quot; $4}
/^C40 /{print a1,$3,$5;print a2,$3,$5}

Thanks for suggestions guys! Ygor: why did you add this test:
if (SP>=$7 && SP<=$9 && CDP>=$3 && CDP<=$5) ?

I was trying to guess what you meant by: &quot;the same with different values many times&quot;.

Ygor,

What I mean is that the data I have is based on the example I gave repeated many times like and I don't think your test works because I get no values for OTH sometimes.

Below is a longer example
