GetFieldCount

GetFieldCount

Returns the field count within a giving segment.

Syntax

[ nFieldCount = Integer] = object.GetFieldCount [ nMsgId = Integer]

The GetFieldCount method syntax has these parts:

Part	Description
object	An object expression that evaluates to the HL7 control.
nMsgId	A integer expression that specifies the message Id.

Returns

Value	Description
nFieldCount	A integer expression that will contains the field count for a giving segment.

Remarks

GetFieldCount of an object is initiated at runtime. The GetFieldCount is called to get the number
of fields within a giving segment.
