A control variable is is defined with format C and can be
used to assign field attributes dynamically. It could be
assigned during the map design (element level) as well as
during the programming (statement level).

Example :
DEFINE DATA LOCAL
1 #ATT(C)
1 #A
END-DEFINE
MOVE (AD=I CD=BL) TO #ATT
INPUT #A (CV=#ATT)
