Convert latitude and longitude from degree to UTM ZONE

[dipand]

Hello to all,
I need to convert latitude and longitude expressed in degrees into UTM zone.
I use the code used in this form:

data have;

id=1; lat=45.5; long=73.5;

run;

proc gproject latlon degrees westlong

project=proj4 to="EPSG:32618"  /* WGS 84 / UTM zone 18N */

data=have out=want;

id id;

run;

proc print data=want noobs; run;

but if I have some latitude and longitudes that do not fall as indicated in the instruction:
project=proj4 to="EPSG:32618" 
how can i do to convert correctly? there's a way? Thank you all

Not sure what you are asking- could you explain more?

Are you asking about how to screen your data before you run gproject on it?

data have;
   input id lat long;
datalines;
1 45.5 73.5
2 55.5 63.5
3 65.5 53.5
4 75.5 43.5
5 85.5 33.5
;
run;

proc gproject latlon degrees westlong
	project=proj4 to="EPSG:32618"
	data=have out=want;
	id id;
run;
