REFERENCE FILE for T41037 (Figure 7). 
This confirms that T41037 is the test for obtain- 
ing SGPT. The computer also stores zero animal, 
specimen and device codes in the DAYFILE 
since a new test is to be executed. It also stores 
the current data so that the date need not be 
keyed in if it is current, and, finally, it places a 
computer version of the code T41037 in the 
DAYFILE to make this part of the context of 
any data v^^hich follows. The user then follows 
instructions and keys in an ! (Figure 8). The ! 
mark is one of the special symbols referred to 
earlier. It indicates that the computer wishes to 
execute the test whose context is current for the 
keyboard, in this case, test T41037. 
Each test execution may call for one or more 
displays (each stored in the REFERENCE 
FILE) to guide entry of further context and 
data, for sampling of an analog channel, and 
for processing of the entered or read data. In 
the case of test T41037, the display shown in 
Figure 9 is generated. Notice that the user has 
been requested to key in certain context codes, 
required in this test, namely animal code, date 
and time, as well as a number of data items. 
Figure 10 shows the display after two of the 
context codes have been keyed-in and with the 
third ready to be keyed in. Keying in the A code 
causes an A with a binary number correspond- 
ing to the keyed in number to be stored in the
