Here is how you get all fields in the clipboard, so you can paste them in your code:

********************************************************************
*  Description.......: FieldsToString - creates a string with fields in a table
*  Calling Samples...:

FUNCTION FieldsToString
LPARAMETERS tlAddTypes, tlAddAlias

LOCAL lcStr, lnI, lnFields, laFields[1], lcType
lnFields = AFIELDS(laFields)
lcStr = ""

FOR lnI = 1 TO m.lnFields
	lcType = laFields[m.lnI,2]
	lcStr = m.lcStr + ", " + IIF(m.tlAddAlias,ALIAS() + ".", "") + ;
		LOWER(LEFT(laFields[m.lnI, 1],1)) + ;
		PROPER(SUBSTR(laFields[m.lnI, 1],2)) + ;
		IIF(m.tlAddTypes, " " + m.lcType + ;
		IIF(NOT INLIST(m.lcType, "D","T","I","G","M","Y"), "(" + TRANSFORM(laFields[m.lnI,3]) + ;
		IIF(laFields[m.lnI,4] > 0, ", " + TRANSFORM(laFields[m.lnI,4]),"") + ")",""),"")
NEXT
_CLIPTEXT = SUBSTR(m.lcStr, 3)

Open your table and type in command window FieldsToString(). Then you would have all your fields in the clipboard.
