Register 01 (lines 12, 13) also acts as a loop counter, but counts ten readings per
set (Register 00). The value 11.020 stored into register 01 specifies registers 11
through 20 as temporary storage registers for the measurement data. Line 15 trig-
gers the 3468A and line 16 inputs the results. Line 17 stores the data in the
register pointed to by Register 01. Register 01 is incremented after each reading
to point to the next empty register in line 18.
Register 01 is also tested in line 18. Remember that program line 12 specified
Register 20 as the last register to be used. If Register 01 points to register 21
then the program prepares to store the ten readings on the cassette. Line 20 calls
out register 11 through 20 as data storage registers. The WRTRX command (line
21)
writes
the
data
from
the
storage
registers
to
the
cassette
tape.
Register OO is tested in line 22 to see if ten sets of ten readings each have been
made, If not, the program loops back (line 23) to label 01 (line 11). When ten
sets of measurements have been made, the program ends.
