SAS NotDigit Function Example

What is it?

• The NotDigit function locates the first instance of a non-number in a string and returns the character position
• If the first instance of a character is the 9th character in the string, the function would return 9
• Similar to the AnyDigit function, counting is from left to right

Syntax:

• NotDigit('String');
