Handbook of SAS DATA Step Programming

97Array Processing

ARRAY statement creates six new DATA step variables, ABOVE1 through

ABOVE6. The third ARRAY statement creates temporary data elements used

only for comparison purposes.

Program 6.6:

data ex6_6(drop = i);

set sbp2;

array sbp[6];

array above[6];

array threshold[6] _temporary_ (140 140 140 120 120 120);

do i = 1 to 6;

if (not missing(sbp[i]))

then above[i] = sbp[i] > threshold[i];

end;

run;

title 'Creating variables ABOVE1 − ABOVE6';

proc print data = ex6_6;

run;

Output from Program 6.6:

Creating variables ABOVE1 − ABOVE6

a a a a a a

b b b b b b

s s s s s s o o o o o o

O b b ...
