Data When the "visible" register of the expression stack is empty the display is blank. On entry up to 13 digits can be displayed, plus sign and decimal point. When an exponent is entered only ten mantissa digits are shown. On output either fixed or scientific notation can be selected, with the number of digits to the right of the decimal point prescribed (0-9). A maximum of ten mantissa digits are displayed. When space allows, digits are grouped by threes with a blank between groups. The sign is always adjacent to the leftmost digit, and in scientific notation the mantissa is right justified with one blank between it and the exponent if space allows. When the exponent is less than ten only one digit is displayed. Examples: -1234567890123. -1 234.567 89 -12 345.67 E-3 -12345.67890E-12 -1.3 E 27 2. Error When an error occurs, or is predicted, the word "Error" is displayed along with a two digit code (of the form <category>.<member>) identifying the error. If the error is one to which the user can give different responses for different results (e.g. request application of a standard fixup) an "r" is appended to the code. Examples: Error 1.2 Error 5.1 r 3. Parentheses When the last entry made in the expression is a left parenthesis the display shows the number of adjacent left parentheses that have been entered. Example: 2- 4. LAST KEY Entering this command causes the keycode of the preceeding key to be displayed. Example: ......018...... 5. Function reference When a function reference is entered into an expression the display indicates the keycode of the function and shows how many arguments are required/allowed. If the function reference is preceeded by a unary minus the sign is shown. Examples: - .047.1 .044.2 .049.2-6 DISPLAY FORMATS (continued) A. RUN mode (continued) 6. Extended sequence When an extended sequence is being entered (e.g. →*R23) the keycode of the last key entered is displayed set off by -'s to distinguish it from the LAST KEY display. Example: ------031------ B. EDIT mode The same display features as in RUN mode apply in this mode except that the program step number is shown in the leftmost four digits. Thus the effective display size is twelve characters instead of sixteen. 1. Data Examples: 0027-1234567890. 1094-1234.56789 0011 1 234. E-3 0123-12345.6E-12 0076 -1.3 E 27 2.

Extended sequence Example: 0075---031------ 7. ENTER The reference number (0-9) for the entry is displayed along with the program step number. Example: 0530...E7....... 8. Program viewing The program is displayed three steps at a time with the center code corresponding to the program step number shown. When the program step number corresponds to the first or last instruction in the memory only two steps are displayed. Examples: 1023-047.018.013 1024-018.013. 0000- .001.002.
