E-18 Data File Organization and Addressing
The following figure shows a user-defined file within Data File 0- Output
Image. We used this particular data file configuration in regard to I/O
addressing on page B-12. Here, we are defining a file 5 elements long.
Note that for the output file (and the input file as well), an element is always
one word, referenced as the slot and word taken together. For example,
element O:3.0 refers to output file, slot 3, word 0. This defaults to O:3, where
word 0 is implied.
Numeric Constants
You can enter numeric constants directly into many of the instructions you
program. The range of values for most instructions is -32,768 through
+32,767. These values can be displayed or entered in several radixes. The
radixes that can be displayed are:
• integer.
• binary.
• ASCII.
• hexadecimal.
