* The simplest, and perhaps most efficient but error-prone method is:
m.lcInString = "C3D1"
m.lcOutString = ""
for m.lpCount = 1 to len(m.lcInString)
do case
case substr(m.lcInString,m.lpCount,1) = "0"
m.lcOutString = m.lcOutString + "0000"
case substr(m.lcInString,m.lpCount,1) = "1"
m.lcOutString = m.lcOutString + "0001"
case substr(m.lcInString,m.lpCount,1) = "2"
m.lcOutString = m.lcOutString + "0010"
case substr(m.lcInString,m.lpCount,1) = "3"
m.lcOutString = m.lcOutString + "0011"
case substr(m.lcInString,m.lpCount,1) = "4"
m.lcOutString = m.lcOutString + "0100"
etc.
endcase
endfor
