Simplified awk script for if else statements
Hi,

The below awk script that i did is working fine. It gives me the results that i want. But, the script is not smart and very long as i have 8 conditions to meet. The sample script below only show 2 conditions.

Code:
awk 'BEGIN{FS=OFS=" ~ |\t"} 
{if (($7>$9) && ($6>$8)){
	Ql= $7-$6; 
	Sl= $9-$8;	
	Hl = $9-$6;
	Qc= (Hl/Ql)*100;
	Sc= (Hl/Sl)*100;
	{if(Sl>Ql){
	Max = Sl;	
	Diff = ((Sl-Ql)/Max)*100;}
	else {
	Max = Ql;
	Diff = ((Ql-Sl)/Max)*100;}
	print $0"\t"Qc"\t"Sc"\t"Diff;}}
else if (($9>$7) && ($8<$6)){
	Ql= $7-$6; 
	Sl= $9-$8;
	Hl = $7-$6;
	Qc= (Hl/Ql)*100;
	Sc= (Hl/Sl)*100;
	{if(Sl>Ql){
	Max = Sl;	
	Diff = ((Sl-Ql)/Max)*100;}
	else {
	Max = Ql;
	Diff = ((Ql-Sl)/Max)*100;}
	print $0"\t"Qc"\t"Sc"\t"Diff;}}
else
	print "error";
}'

sample inputfile

Code:
174.14A.1	A10gh1	174.14A.1.11	22	24	489 ~ 1908	264 ~ 1654	75.03%	0.0	2448	ion channel (don) fam.
174.14A.1	A3g130	174.14A.1.50	5	6	75 ~ 656	33 ~ 672	94.81%	1e-126	1007	dressrossa don fam
201.1A.66	A17l50	201.1A.66.33	7	9	19 ~ 586	32 ~ 628	76.25%	1e-119	962	dressrossa don fam

Sample output
Code:
174.14A.1	A10gh1	174.14A.1.11	22	24	489 ~ 1908	264 ~ 1654	75.03%	0.0	2448	ion channel (don) fam.	82.10	83.81	2.04
174.14A.1	A3g130	174.14A.1.50	5	6	75 ~ 656	33 ~ 672	94.81%	1e-126	1007	dressrossa don fam	100.00	90.92	9.08
error

I don't have any problem with the output, all i want to know is much better way to simplify this in awk. Can anyone help/advise me about this. Thanks
