UNITED STATES NATIONAL MUSEUM BULLETIN 285 



the minima specified for the x and y variables 

 in each plot. The difference between the min- 

 imum and maximum (Instruction 12) speci- 17. (0-7) 

 lied for each variable determines the scale of 

 calibration of each scatter diagram in which 

 these variables are plotted. (See explanation 

 of sample output from VPLOT. ) The cards 

 are read in according to the same format as 

 that used for the reading in of the data deck 

 and must therefore be punched in the same 

 way as the data cards, with a specimen num- 

 ber being entered as the first variable. 



12. ( 1- ) : Cards containing the anticipated maximum 



values for each of the variables in the input 

 array, as explained in Instruction 29 in the 

 description of DASAN. These values, together 

 with the minimum values specified for each 

 variable ( Instruction 11), determine the scale 

 to which the axes of each of the scatter dia- 

 grams are calibrated. These cards are read in 

 according to the same format as that used for 

 the reading in of the data deck and must 

 therefore be punched in the same format as 

 the data cards, with a specimen number be- 

 ing entered as the first variable. 



13. (1) : The number of columns of variables (from 



to 60 ) which are to be replaced by their loga- 

 rithms (base 10). Punch in columns 2-3. 



14. (1) : The number of columns of variables (from 



to 60) which are to be transformed to loga- 

 rithms, with the logs being entered as new col- 18. 

 umns of data and the original values being 

 preserved. Punch in columns 2-3. 



15. (0-2) : Column identification numbers of the vari- 



ables which are to be replaced by their loga- 19. 

 rithms. Punch in fields of 2 columns in col- 

 umns 1-72 of the first card and in columns 

 1-48 of the second card. 



16. (0-2) : Column identification numbers of the vari- 



ables which are to be transformed into loga- 20. ( 1 ) : 

 rithms and entered as new columns of data in 

 the internal arrav. Punch in fields of 2 col- 



umns in columns 1-72 of the first card and in 

 columns 1-48 of the second card. 

 Cards containing a minimum log value for 

 each variable in the input array which will 

 be transformed to a logarithm and for which 

 a zero minimum was specified in Instruction 

 11. This log minimum will be inserted by the 

 program into any blank data cells and, like the 

 minima for non-log data described in Instruc- 

 tion 11, will determine the coordinates of the 

 origin and the calibration of the axes of each 

 diagram. 



If the minimum specified for a variable in 

 Instruction 11 is greater than zero, the log of 

 this value will become the log minimum, and 

 it is not necessary to specify any new log mini- 

 mum here. The maximum value for each log 

 variable is the log of its maximum previously 

 specified in Instruction 12. 



Punch an imaginary specimen number in 

 columns 1-4 and the log minima in fields of 7 

 columns in columns 5-67 of the first card and 

 in columns 1-70 of each succeeding card. Con- 

 secutive fields represent consecutive columns 

 in the input array, so that a minimum for the 

 7th variable, for example, must be punched 

 in the field which is in columns 40-46. 



The decimal point will be placed by the 

 program in front of the last four digits of each 

 log minimum. 



If more plotting groups remain, enter one in- 

 formation card (Instruction 7) for each 

 group. Punch as described in Instruction 7, 

 placing a / in column 72. 

 If more data decks remain to be processed 

 having the same numbers of variables in the 

 input and internal data arrays and the same 

 names for the variables, begin again with In- 

 struction 4. 



If no more data decks remain, the last card 

 consists of the word FINISH punched in col- 

 umns 1-6. 



Sample Input Data for VPLOT 



Listed below are the control and data cards for a test run 

 of VPLOT, the output from which is discussed in the fol- 

 lowing section. The input data is the univariate output ar- 



ray punched by the preceding test run of DASAN. On the 

 far right side of each control card are numbers which refer 

 to instructions in the section on input preparation.
