Details

Names for variables and labels should adhere to the following rules in Amiga Basic:

• Length of the names should be in the range of 1 up to 255 character

• Names cannot be AmigaBasic.reserved() words

• Names should only contain alphanumeric characters or periods and should not contain special characters (i.e., reserved for type definition, such as dollar- or percentage sign)

• Names should not start with a numeric character

This function tests names against each of these criteria.
