FIELDS S-l, S-Z, and S-3 

 Columns 54, 55, and 56 



FIELD S-l 



Several of the items of the common Code list for Fields S-l, S-2, and S-3 are not ordinarily 

 applicable for describing the administration of inocula. In particular, Symbols C and M have been 

 designated in the Code as not being used in Field S-l. Thus, Symbols C, M, and the IBM 11 and 12 

 zone punches are available for additions to Field S-l. 



6. File of coded biology data on IBM punched cards arranged according to symbols for routes 

 of administration 



The CBCC has established no separate files of biology data arranged by entries in Field S-l, 

 S-2, or S-3. 



7. Double coding in Fields S-l, S-2, and S-3 



If more than one route of administration of inoculum or implant, secondary compound, or test 

 compound (Fields S-l, S-2, and S-3, respectively) have been employed and the results of the tests 

 using the different routes are so similar that the coding for the tests would be identical except for the 

 entry in Field S-l, S-2, or S-3, both routes can be coded in that field to accommodate both tests in a 

 single code line. This coding of two or more tests in a single line is referred to as double coding. 

 HOWEVER, double coding in these three fields is possible only if the code symbols for both of the two 

 routes are numerical, i. e. , any of Symbols and 1 through 9; if one or both of the routes is coded by 

 a letter symbol (Symbols A through Z), a separate code line must be constructed for each test using a 

 different route of administration. If Field S-l, S-2, or S-3 is double coded with more than one of 

 Symbols and 1-9, both or all of the coded symbols are punched on the same IBM card in the column 

 for the field.
