http://docsrv.sco.com/SDK_charm/_Setting_and_Reading_Field_Buffe.html says:
| The function field_buffer always returns the correct value if the field

| sometimes inaccurate because data is not moved to field buffer 0

|   routines, if any
| * it is called just after a REQ_VALIDATION request to the form driver 

(Is that documented anywhere else?)
