FIELD K 

 Column 43 



SEX AND STAGE OF DEVELOPMENT OF THE HOST ORGANISM 



The organization, general use, and, for the most part, the specific directions and explanations 

 for Field K are so nearly like those for Field F that repetition is unnecessary. Keeping in mind that 

 coding in Field K describes the host in Field J, the discussions of Field F (describing the test organism 

 in Field E) can be interpreted to apply to Field K. It will be noted that any reference to Symbols S 

 through Z does not apply to Field K, for which reason none of Division 5 of the Specific Directions and 

 Explanations for Field F is applicable to Field K. 



As in the case of Field F, the CBCC maintains no file of coded data (IBM punched cards) 

 arranged by code entries in Field K. 



Double coding is permitted in Field K, just as double coding is permitted in Field F as described 

 in Division 4 of Field F.
