Answer / bakul shah

Another way to call Subroutine.
Example:
*========================================================
* Bakul Shah
* HOW MANY DIFFERENT WAYS IT IS POSSIBLE TO MAKE
* CHANGE FOR A DOLLAR? ---> 292 Posibilities ??
*
* H HALF DOLLAR
* Q QUARTER
* D DIME
* N NICKEL
* P PENNY
* A LOOP - INITIALIZE TO ZERO
* NO LINE NUMBER - INITIALIZE TO 55
* KOUNT TOTAL NUMBER INITIALIZE TO ZERO
* ;

/* The file 'c:coinpage.txt' is:
File Name=C:\WINDOWS\system32\coinpage.txt,
RECFM=V,LRECL=256 */

Data Null_ ;
/* file 'c:coinpage.txt'; */
File CoinPage ;
A=0 ;
PageCount = 0 ;
NO=55; Retain NO;
KOUNT=0;
DO H = A to 2; /* Half Dollar */
DO Q = A to 4; /* Quarter */
DO D = A to 10; /* Dime */
DO N = A to 20; /* Nickle */
DO P = A to 100; /* Cents */
IF(((H*50)+(Q*25)+(D*10)+(N*5)+P)=100) THEN
do;
KOUNT+1 ;
If NO > = 55 then
do;
Link PageHeader;/* Calling Subroutine*/
end;
NO+1 ;
Put @9 KOUNT 3. @18 H 3. @27 Q 3.
@36 D 3. @45 N 3. @54 P 3. ;
end;
end;
end;
end;
end;
end;
Return;

PageHeader: /* Subroutine */
PageCount + 1 ;
Put @70 'Page' +0 PageCount 2.
/@8 'KOUNT' @20 'H' @29 'Q' @38 'D'
@47 'N' @56 'P' ;
NO = 0 ;
Return;
Run;

Answer / prakhar

SAS code could be linked using the GOTO or the Link statement.

The difference between the LINK statement and the GO TO statement is in the action of a subsequent RETURN statement. A RETURN statement after a LINK statement returns execution to the statement that follows LINK. A RETURN statement after a GO TO statement returns execution to the beginning of the DATA step, unless a LINK statement precedes GO TO, in which case execution continues with the first statement after LINK. In addition, a LINK statement is usually used with an explicit RETURN statement, whereas a GO TO statement is often used without a RETURN statement.

When your program executes a group of statements at several points in the program, using the LINK statement simplifies coding and makes program logic easier to follow. If your program executes a group of statements at only one point in the program, using DO-group logic rather than LINK-RETURN logic is simpler.

Goto eg.

data info;

input x;

if 1<=x<=5 then go to add;

put x=;

add: sumx+x;

datalines;

7

6

323

;

Link Eg.



data hydro;

input type $ depth station $;

/* link to label calcu: */

if type =’aluv’ then link calcu;

date=today();

/* return to top of step */

return;

calcu: if station=’site_1′

then elevatn=6650-depth;

else if station=’site_2′

then elevatn=5500-depth;

/* return to date=today(); */

return;

datalines;

aluv 523 site_1

uppa 234 site_2

aluv 666 site_2

…more data lines…
