Determining the Number of Maps in the Current Frame
Syntax tpmapcount()
See Also tpplot , tpmacrostring

Description
Returns an integer scalar specifying the number of maps in the current Tecplot frame.

Examples
If you enter
   clear
   tpopen
   x = 0. : .1 : 2 * pi
   y = cos(x)
   ix = 0.2
   while (ix < 6.0) begin
      m =tpplot(x+ix,y)
      ix = ix + 1
      print "tpplot() created map number: ", m
   end
O-Matrix will create 6 curves, with 6 line maps and echo the number of each map as it is created,
tpplot() created map number:  1 
tpplot() created map number:  2 
tpplot() created map number:  3 
tpplot() created map number:  4 
tpplot() created map number:  5 
tpplot() created map number:  6 
If you continue by entering
   tpmapcount
O-Matrix will echo 6 which is the number of maps in the current frame after executing the example above.

The tpmapcount function can also be used to determine the number of maps in existing data sets or files. If you enter,
   tpopen([OM_INSTALL,"\example\tecplot\rainfall.plt"])
   print "Number of maps in rainfall.plt = ", tpmapcount
O-Matrix will echo
   Number of maps in rainfall.plt =  5
which is the number of map in the rainfall.plt sample data file.
