>Is there a function that will return how many decimal places a numberic field has? Something like LEN() for a character field. I know I can get it with AFIELDS but I only want to check one field and this returns all the fields then I need to find what the field number is in the array. Seems like a pain for something this simple.

AFAIK, no other way than AFIELDS without maybe some low level functions to read the header info. Just create a function yourself that uses afields and accepts a field name as a parameter.
