Reference Manual > Entry rules

Questions will normally have a number as part of the name.

You can set a Project global Controls option to warn if entry names are longer than a set number of characters.

If entries are cut and pasted to a different position in the questionnaire file, or entries are added or deleted during the design phase, [Edit] [Rename] from the Main window may be used.

IMPORTANT: the following special characters should never be included in entry names:

•* (asterisk)

•/ (forward slash)

•\ (backward slash)

•^ (carat)

•~ (tilde)

•! (exclamation mark)

• (space)

•" (double quote)

•' (single quote)

•- (minus) if referred to in arithmetic definitions in integer variables or float variables

•£ (pound sign)

•$ (dollar sign)

•& (ampersand)

•( (open parenthesis)

•) (close parenthesis)

•{ (open brace)

•} (close brace)

•: (colon)

•; (semi-colon)

•@ (at sign)

•< (less than)

•> (greater than)

•? (question mark)

•# (hash sign)

For questions to be recorded by Invade the following characters must not be used:

•- (minus sign)

•| vertical bar

We recommend that you begin each question with a letter (such as Q), especially if you wish to export data to other programs, for example SPSS.

Whenever possible, filters and variables should be given names that identify their contents.

TIP: to make the different types of entry immediately recognisable in a list of entries we recommend:

•question names begin with the letter Q

•filter names begin with the letter F

•variable names begin with the letter V

You can set a Project global option to upper case all new entry names.
