ANY* and NOT* Function

The ANY* and NOT* functions find specific characters within a character string. The set of characters that the functions find is based on the translation table used by SAS, and whether the session is run in an ASCII or EBCDIC environment. To determine which characters are found in your session of SAS, use the following program. Values of 1 mean that the character is found by the function, values of 0 mean the character is not found.

data test;
      do dec=0 to 255;
           byte=byte(dec);
           hex=put(dec,hex2.);
           anycntrl=anycntrl(byte);
           anygraph=anygraph(byte);
           anypunct=anypunct(byte);
           notalpha=notalpha(byte);
           notprint=notprint(byte);
         output;
      end;
run;

proc print data=test;

PROC SURVEYSELECT

Simple random sample without replacement
Select a random sample where no observation can be chosen more than once.

/* WORK.EASTHIGH is a data base of student grade point averages */
/* from East High School, Grades 9 through 12, 100 or more students per grade. */

data EastHigh;
      format GPA 3.1;
      do Grade=9 to 12;
            do StudentID=1 to 100+int(201*ranuni(432098));
                  GPA=2.0 + (2.1*ranuni(34280));
                  output;
            end;
      end;
run;

/* Using PROC SURVEYSELECT */
/* Use METHOD=SRS. N= is the number of observations to select. */
/* The sample is stored in the OUT= data set, SAMPLE1. */

proc surveyselect data=EastHigh method=srs n=15 out=sample1;
run;

Changing titles in ODS Content Page

For those who use the HTML content frame, it can be quite annoying to see a bunch of PROC PRINT or PROC GPLOT in the content page. To change the titles, you can use the following statement.
ODS PROCLABEL ""; 
The PROCLABEL statement also has utility in the PDF destination as it can be used to alter the text in the contents panel.

SAS Qualification Tools

Using two tools to verify SAS installed correctly and operational. The two tools are the SAS Installation Qualification Tool (SAS IQ) and the SAS Operational Qualification Tool (SAS OQ).
  • The SAS IQ assists in demonstrating the SAS System has been installed and maintained to the manufacturer's specifications. SAS IQ verifies the integrity of each file in the SAS System 9 and provides the customer a set of reports detailing the results.
  • The SAS OQ assists in demonstrating the SAS System is operational. SAS OQ uses SAS programs provided by the component development groups and will execute, process, and report the program results.
