The SASECRSP Interface Engine

Example 35.1 Specifying PERMNOs and RANGE on the LIBNAME Statement

The following statements show how to set up a LIBNAME statement for extracting data for certain selected PERMNOs during a specific time period. The result is shown in Output 35.1.1.

title2 'Define a range inside the data range';
title3 'My range is ( 19950101-19960630 )';

libname _all_ clear;
libname testit1 sasecrsp "%sysget(CRSP_MSTK)"
        setid=20
        permno=81871    /* Desired PERMNOs are selected   */
        permno=82200    /* via the libname PERMNO= option */
        permno=82224
        permno=83435
        permno=83696
        permno=83776
        permno=84788
        range='19950101-19960630';
