What's the max # of columns in cursor?

>The values are fixed (numeric 1-5), which simplifies things.
>The cursor's column names do not exceed 10. I rotated the column names 315 degress, so it looks pretty decent.
>
>The expression to display a column looks like the following. It is repeated for each column but the column number check is incremented:
>IIF(USED('cursor') AND FCOUNT('cursor') >= 4,FIELD(4,'cursor'),'')
>
>The expression to display a value for a column looks like the following (for the column example above):
>NVL(IIF(USED('cursor') AND FCOUNT('cursor') >= 4,EVAL("cursor."+FIELD(4,'cursor')),''),'NA')
