IMHEADER appears to look at both the clean product code and the number of 
iterations to decide what the type of the map is. If the number of iterations
is zero, IMHEAD will report "Map type = DIRTY" no matter what the clean
product code is set to. If you try

KEYWORD  = 'NITER'
KEYVALUE = 100, 0
PUTHEAD

The map type should switch to NORMAL.
