Variable Names for variable data files

The following rules apply to Variable names when editing a variable data file in WinCross:

Each variable name must be unique.
The maximum variable name length is 64 characters.
The first character must be a letter or the character @.
The characters # or $ are acceptable if the data file is opened with these characters as the first position of the variable name.
Middle characters of the variable name can be any combination of letters, numbers, @, #, $, comma (,), period (.) or underscore (_).
The last character of a variable name cannot be a period (.) or underscore (_).
Spaces are not allowed in variable names.
SPSS reserved keywords cannot be used as variable names. SPSS reserved keywords are ALL, AND, BY, EQ, GE, GT, LE, LT, NE, NOT, OR, TO, and WITH.
Variable names can contain any mixture of uppercase and lowercase characters and the case will be preserved in the SPSS data file.
Variable names cannot use reserved key words. NET, SUB, TN, CALC are all examples of Reserved Key Words.
Do not use I followed by a number (example, I3 or I30) for variable names.
