#!N #!N One of the most useful tools for debugging visual 
programs is the Print module. For example, if you are getting 
an error from a module that a particular field is inappropriate 
for processing, you can print out the object to see if 
it is what you expect it to be. Print can be 
used to see the structure of and data values in any 
object. The options parameter is used to set the level of 
detail printed: the default "o" prints just the top level object: 
for example "Field with 4 (four) components." If options is set 
to "r," more information about each component is printed, for example, 
how many items in each component, and the data type. You 
can also print out some or all of the values in 
the components. #!N #!N The output of Print appears in the 
Message window. #!N #!N #!N  #!F-adobe-times-medium-i-normal--18*   Next Topic #!EF #!N #!N
