Q
Out;
Data2 
CP
In;

Q
Out;
Data3 
CP
In;
CPN
In;

In;
QN
Out;

I want my output as

Data1(C,CP,D,Q)
In C;
In CP;
In D;
Out Q;
Data2 (CP,D,Q)
In CP;
In D;
Out Q;
Data3 (CP,CPN,D,QN)
In CP;
In CPN
In D
Out QN;

I tried code given in comment section below, But getting error. Corrections are welcome.

回答1:

variation on @EdMorton suggestion - fixing the desired order of fields:

$ awk 'FNR==1{print;next}!(NR%2){a=$0; next} {printf "%s %s%s%s", $1,a,FS,ORS}' FS=';' file
Data
In A1;
In A2;
Out Z;
