Using masks in string variables
Dec 4, 2023
Using masks for string variables is allowed. When creating masks, you can use the following regular expressions:
- Wildcard character (*)—Any string of 0 or more characters.
- Question mark (?)—Any single character.
- [<range>]—Any single character from a specified range or set.
For example: [0–9]—Any digit. [abcdef]—Any of the characters a, b, c, d, e, or f.
