NOTPRINT Function

Searches a character string for a non-printable character and returns the first position at which it is found

Category: Character

Syntax

NOTPRINT ( string <, start >)

Arguments

string

• is the character constant, variable, or expression to search.

start

• is an optional integer that specifies the position at which the search should start and the direction in which to search.

Details

The results of the NOTPRINT function depend directly on the translation table that is in effect (see 'TRANTAB= System Option' on page 1617) and indirectly on the ENCODING and LOCALE system options.

The NOTPRINT function searches a string for the first occurrence of a non-printable character. If such a character is found, NOTPRINT returns the position in the string of that character. If no such character is found, NOTPRINT returns a value of 0.

If you use only one argument, NOTPRINT 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 the following 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.

NOTPRINT returns a value of zero when

• 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 NOTPRINT function searches a character string for a non-printable character. The ANYPRINT function searches a character string for a printable character.
