| Restriction: | This function is assigned an I18N Level 1 status. If possible, avoid I18N Level 1 functions if you are using a non-English language. Under certain circumstances, the I18N Level 1 functions might not work correctly with Double-Byte Character Set (DBCS) or Multi-Byte Character Set (MBCS) encodings.

Syntax
Required Argument
string
is the character constant, variable, or expression to search.
Optional Argument
start
is an optional integer that specifies the position at which the search should start and the direction in which to search.
Details
The ANYPRINT function
searches a string for the first occurrence of a printable character.
If such a character is found, ANYPRINT returns the position in the
string of that character. If no such character is found, ANYPRINT
returns a value of 0.
If you use only one
argument, ANYPRINT begins the search at the beginning of the string.
If you use two arguments, the absolute value of the second argument, start,
specifies the position at which to begin the search. The direction
in which to search is determined in this way:
-
If the value of start is positive, the search proceeds to the right.
-
If the value of start is negative, the search proceeds to the left.
-
If the value of start is less than the negative length of the string, the search begins at the end of the string.
ANYPRINT returns a value
of zero when one of these conditions is true:
-
The character that you are searching for is not found.
-
The value of start is greater than the length of the string.
-
The value of start=0.
Comparisons
The ANYPRINT function
searches a character string for a printable character. The NOTPRINT
function searches a character string for a nonprintable character.
Examples
Example 1: Searching a String for a Printable Character
This example uses the
ANYPRINT function to search a string for printable characters.
data _null_;
string='Next = _n_ + 12E3;';
j=0;
do until(j=0);
j=anyprint(string, j+1);
if j=0 then put +3 "That's all";
else do;
c=substr(string, j, 1);
put +3 j= c=;
end;
end;
run;SAS writes the following
output to the log:
j=1 c=N j=2 c=e j=3 c=x j=4 c=t j=5 c= j=6 c== j=7 c= j=8 c=_ j=9 c=n j=10 c=_ j=11 c= j=12 c=+ j=13 c= j=14 c=1 j=15 c=2 j=16 c=E j=17 c=3 j=18 c=; That's all
Example 2: Identifying Control Characters By Using the ANYPRINT Function
You can execute this
program to show the control characters that are identified by the
ANYPRINT function.
data test; do dec=0 to 255; byte=byte(dec); hex=put(dec,hex2.); anyprint=anyprint(byte); output; end; proc print data=test; run;
