SAS language for dummies — four main programming methods

Programming

In this example, Dollar6.2 Information informs SAS how to interpret the value (only six signs, with two decimal signs and a place for a currency symbol).

-transformation-transformation Simal value in the date of date. This is just a complex special case of the first advice, since in SAS the value of the date is the number. To convert it to the date, you use Date Informat:
data conversion;
The length of DateVal 8;
Dateval = Input («10 Yang2025», Date9.);
run;

— calculating the new date value relative to the given date. When the date value is a number, you can use the functions of Intnx and the implementation of “dates mathematics”. For example, this program calculates a new date, which is 60 days from the initial date, and then calculates how many Mondays are for this interval:
data conversion;
Datevar 8 NEXTDATE 8;
DateVar Date9 format. NextDate Date9.;
Datevar = '01Jan2025'D;
nextdate = Intnx (' Day ', DateVar, 60);
MONTERS = IntCK (' Week1.1 ', DateVar, NextDate);
RUN;

— a random number generation. The Rand function contributes to a universal tool for generating random numbers with any distribution or range. For example, to generate a random number from 1 to 100, use:
x = rand ('whole number', 1.100);
perform the SAS function outside the DATA step. SAS functions are usually used to calculate and convert values ​​in the DATA step. You can use %SYSFUNCMAROFUNCION to call the SAS function anywhere in the open code. For example, to show the current time in the Title operator, use something like this:
Topic ”The result is obtained in %SYSFUNC (Time (), TimeAmpm.)»; SAS for dummies — four main programming methods
