# Character Acceptance List

> [HTML Version](characteracceptancelist.htm)

_setdef_ may specify a list of acceptable characters rather than complete field entries. To use this method, specify the **\{** code and then load _setdef_ with a string of the characters you want to accept. Note that any input characters must first pass the normal _type_ code test and then must be in the _setdef_ string, so you may wish to specify the A _type_ code as well. For example:

setdef = " 123ABCabc+-"

This would limit input to the numbers 1, 2, and 3; the letters A, B, C, a, b, and c; the plus sign, minus sign, and space. Note that upper and lower case must be listed independently.
