The SASECRSP Interface Engine

This example shows how to use the CRSP date functions and formats. The CRSPDTD formats are used for all the crspdt variables, and the YYMMDD format is used for the sasdt variables.

/* Call the CRSP date to Integer function*/

/* Call the SAS date to Integer function*/
   intdt3 = crspds2i(sasdt);

/* Call the Integer to CRSP date function*/
   crspdt2 = crspdicd(intdt,exact);

/* Call the SAS date to CRSP date conversion function*/
   crspdt3 = crspdscd(sasdt,exact);

/* Call the CRSP date to SAS date conversion function*/
   sasdt2 = crspdcsd(crspdt);

/* Call the Integer to SAS date conversion function*/
   sasdt3 = crspdi2s(intdt);

Output 38.6.1 shows the OUT= data set that is created by the DATA step.

Output 38.6.2 shows the contents of the OUT= data set by alphabetically listing the variables and their attributes.
