Finding the Minimum and Maximum of a value

[K_Wils15]

Here is a sample of the data:

Year Month Gasprice

2003 1 1.47

2003 4 2.06

2003 8 1.89

2004 3 2.00

2004 8 2.69

2004 9 3.00

I am tasked with finding the minimum and maximum of each year. so far I have: 

proc means data=work.gas noprint;
var Year GasPrice;
output out=work.minmax
min (Gasprice) = minvt
max (Gasprice)= maxsys;

run;

How do find the minimum and maximum of the gas price per year?

data gas;
input Year Month Gasprice ;
cards;
2003 1 1.47
2003 4 2.06
2003 8 1.89
2004 3 2.00
2004 8 2.69
2004 9 3.00
;

proc means data=work.gas noprint nway;
class year ;
var  GasPrice;
output out=work.minmax
min  = minvt
max = maxsys;
run;

proc print noobs;run;
