Function FieldInfo() Foundation
Sets or returns the settings for a field.
FieldInfo( <nFieldPos>, <nDefine>, ; [<xNewSetting>] ) --> xOldValue
The return value of FieldInfo() is the value for the field setting specified by <nDefine>. If this is a changeable setting and <xNewSetting> is specified, the function returns the old value.
The function FieldInfo() allows information about individual fields (field variables) in a work area to be accessed. To do this, a file must be open in the work area. If there is not an open file, a runtime error is generated when FieldInfo() is called. A detailed description of the information that can be retrieved using FieldInfo() is found in the chapter The Xbase++ Database Engine in the Xbase++ documentation.
