SAS AnyDigit Function Example

What is it?

• The AnyDigit function locates the first instance of a number in a string and returns the character position
• So, if the first instance of a number is in the 5th character in the string, the function would return 5
• The counting is from left to right

Syntax:

• anydigit('String');
