Function definition: (Copy & paste into FileMaker's Edit Custom Function window)

// since there is no zero-equivalent in the alphbet, this function plays a few tricks with the starting positions 
// to make zero-based, base ten input (0-9) conform to one-based, base twenty-six output.
// it is otherwise the same as DecToHex found at http://www.briandunning.com/cf/216

Let ( [
_bit = Mod ( integer ; 26 ) + 1 ; 
_alpha = "zabcdefghijklmnopqrstuvwxy" ;
_char = Middle ( _alpha ; _bit ; 1 ) ;
_next = Div ( integer - 1 ; 26 ) 
] ;

Case ( 
_next ;
NumToAlpha ( _next )
)//end Case
& _char
)//end Let

Converts a number to it's alphabet equivalent.

Since there is no zero-equivalent in the alphbet, this function plays a few tricks with the starting positions to make zero-based, base ten input (0-9) conform to one-based, base twenty-six output. It is otherwise the same as DecToHex found at http://www.briandunning.com/cf/216
