我用公司的电脑来运行filename statement url, 总是出现错误ERROR: 10060 - WSAETIMEDOUT.
公司的SAS版本是9.1的。请个位大侠指点迷津：不知道这样的错误是因为版本问题还是端口问题，如何解决呢？如果是需要设置SAS enviroment URL的话，v9.1在哪里设置呢？谢谢大家了！

code is as below:

* enter two zip codes;
%let z1=12203;
%let z2=20500;
* no changes required below this line;
filename x url "http://maps.google.com/maps?daddr=&z2.%nrstr(&saddr)=&z1";
filename z temp;

data _null_;
infile x recfm=f lrecl=1 end=eof;
file z recfm=f lrecl=1;
input @1 x $char1.;
put @1 x $char1.;
if eof;
call symputx('filesize',_n_);
run;

data _null_;
infile z recfm=f lrecl=&filesize. eof=done;
input @ '<div class="altroute-rcol altroute-info">  <span>'  @;
input text $50.;
distance = input(scan(text,1," "),comma12.);
units    = scan(text,2,"< ");
time     = scan(text,5,"<>");
file print;
put "DRIVING DISTANCE BETWEEN &z1 AND &z2 : "
     distance units" (TIME: " time ")";
stop;
done:
file print;
put "CANNOT FIND THE DISTANCE OR TIME BETWEEN &z1 AND &z2, TRY ANOTHER COMBINATION";
run;

filename x clear;
filename z clear;
