L 1.0- INTRODUCTION AND OVERVIEW 1.1 Introduction The Reload Data Block (RDB) is a group of constants __

A preliminary list of RDB constants is presented in Appendix A to illustrate the types and number of constants expected in the RDB.

A specialized System Loader will be used to load both the CPC/CEAC System Load disk and the Reload Data Block Constants disks.

This document provides guidelines for generating the RDB disk for a given change in RDB constants. It is expected that RDB constants willbechangedinfrequently,((

1.3 Software Overview 1.3.1 The RDB constants disk will be generated by the Reload Data Block Interactive Utility Program. This program contains an RDB Disk Generation Routine and a Disk Comparison Routine. The latter will be used for verification of changes in RDB constants.-

The Disk Generation Routine is designed to generate an RDB disk via a series of questions and answers at the TTY console. The program includes range checking to reduce the chances of mis-entry.

.Upon user request, the program can print a list of changes and/or a complete list of the RDB. constant values cross-referenced with the old values. The complete list will include identification of all constants that have changed, facilitating quality assurance of the final disk.

1.3.2 The RDB Interactive Utility Program will be quality assured to the requirements of Reference 1.2.2.

2.0 RELOAD DATA BLOCK DISK GENERATION

2.1 Purpose

To create a floppy disk containing Reload Data Block constants.

2.2 Prerequisites

System Configuration: CPC SINGLE CHANNEL TELETYPE TERMINAL FLOPPY DISK DRIVE Software: RDB Interactive Utility Program Disk Other Items: Previous RDB constants disk with associated checksum and sequence numbers.

Blank. Disk List of New Constant Values

2.3 Procedure

1) Load the RDB Interactive Utility Program. Refer to Figure 1 for a Pre System 80 plant or to Figure 2 for a System 80 plant.
2) a) Program will print ' ENTER OPERATOR NAME AND DATE' b) Respond with operators name followed by a RETURN and then the date in.MM/DD/YY format followed by RETURN.

c) Program will then print ' LOAD THE RDB GENERATION OR COMPARISON PROGRAM? G/C' d) Respond with 'G', the program will print ' RELOAD DATA BLOCK GENERATION ROUTINE'

3) Program will then print ' INSERT CURRENT RELOAD DATA BLOCK DISK, HIT RETURN WHEN READY'. Insert the current RDB disk in drive 0 and hit RETURN. The program will then load the RDB constants into memory.
4) Respond to the ' ENTER CHECKSUM' prompt with the checksum printed on the TTY output when the current RDB disk was generated.

a) The checksum entered will be compared to the checksum of the constants in memory, ensuring the correct sequencing of the RDB disk updates. If a mismatch does not occur, continue with step 5.

b) If a mismatch occurs, ' CHECKSUM ERROR -- RELOAD OR RE-ENTER L/E' will be printed. Enter 'L' to load again or

'E' to're-enter the checksum. Return to step 3 if 'L' was chosen or repeat step 4 if 'E' was chosen.

5) Respond to the ' ENTER DISK SEQUENCE NUMBER' with the sequence number printed on the TTY output when the current RDB disk was generated.

a) The seouence number entered will be compared to the sequence number on disk. If a mismatch does not occur, continue with step 6.

b) If a mismatch occurs, DISK SEQUENCE NUMBER ERROR -- RELOAD

! OR RE-ENTER L/E' will be printed. Enter 'L' to load again or 'E' to re-enter disk sequence number. Return to step 3 if 'L'~ is chosen or repeat step 5 if 'E' is chosen.

6) ' ENTER CONST/DONE' will be printed. If '00NE' is selected, go to step 11. Otherwise, continue to step 7 i
7) Enter the label of the constant to be changed as it appears in reference 1.2.5. (See notes #1 and #3 at end of this section.)

If the entered label is not found', ' CONSTANT LABEL ERROR' will be displayed and the program returns to step 6.

8) When a match occurs the label and its current value will be printed after which ' CHANGE? Y/N' will be printed.
9) Respond 'N' if the value is not to be changed, respond 'Y' if the value is to be changed. If 'N' is selected, return to step 6. If 'Y' is selected, go to step 10a. .
10) a) Program prints ' ENTER NEW VALUE'. Enter the new value.

(See note #2 at the end of this section.)

b) If an error is made in typing the new value, enter '#' to abort the current value. Then, reenter the value.

c) If the value is not within the pre-defined range for the constant being changed, ' RANGE ERROR' will be printed, and the program returns to step 8. If the value does not meet the requirements of note #2, ' INPUT FORMAT ERROR' wil.1 be printed and the program returns to step 8.

d) If the value is within the pre-defined ranges and of the correct format, the value will be updated and the program returns to step 8.

11) If '00NE' is selected in step 6, ' PRINT CHANGES? Y/N' will be printed. If 'Y' is chosen, the label, old value and new value of the constants which have changed will be printed. If 'N' is chosen they will not be printed.

[

12) 'MORE CHANGES? Y/N' will be printed. If 'Y' is selected, execution returns to step 6. Otherwise execution continues with step 13.
13) ' INSERT NEW RELOAD DATA BLOCK CONSTANTS DISK' will be printed.

Place the new RDB disk in the floppy disk drive and hit RETURN.

The RDB constants, plant identification number, CPC/CEAC software revision number, new disk sequence number, and checksum will be written to the floppy disk.

14) After the new RDB disk has been generated, ' WRITE PROTECT NEW RDB DISK' will be printed. Remove the new RDB disk from drive 0 and write protect it, then replace it in the drive and hit RETURN.
15) After the new RDB disk has been write protected, '0ISK SEQUENCE NUMBER = XXXX' and ' CHECKSUM =.NNNN' will be printed on the TTY. Record both' values as they will be used to uniquely ,

identify this disk and will be used in future RDB changes (steps 4 and 5 above).

16) Next, ' COMPARE?Y/N' will be printed. . If 'N' is selected, the calculator will halt. If 'Y' is selected the Reload Data Block Comparison Routine will be executed starting at step 2 of Section 3.3.

Note #1: Array values are entered in standard FORTRAN notation. Example: The tenth constant of a fifty item array would be entered as 'CONST(10)'.

Note d2: All values are input at the TTY as real numbers either in decimal format or in FORTRAN format.

Examples: The floating point number 100.25 can be entered as ' 100.25', '100.25E+0', 'O.10025E+3', etc.

The integer number 56 can be entered as '56', '56.',

'56.0', '560E-l', '0.56E+2' etc. If an integer is incorrectly entered with a fractional value, ' INPUT FORMAT ERROR' will be printed.

Note #3: Appendix A contains a preliminary list of RDB constants. The list is provided for reference purposes only. Reference 1.2.5 will contain the final list of constants. After approval of Reference 1.2.5, the list will be incorporated in revised versions of References 1.2.3 and 1.2.4.

e APPENDIX A PRELIMINARY RDB CONSTANTS This appendix provides a preliminary list of the CPC/CEAC data base constants that are expected to be included in the Relcad Data Block (RDB). As noted in the list, some of the constants are single values while others are arrays of values. The list includes 240 data base constants which, counting individual.

array members, totals 556 individual values. The final list of RDB constants may differ in small ways from this list. However, the number of constants and/or.the number of values are not expected to change substantially.

The final list of constants will be defined in 'the Software Modification

' document for the Reload Da'es Block (Rcferance 1.2.5) and will be incorporated in revisicns to' the CPC and/or CEAC Functional Design Requirements documents (References 1.2.3 and 1.2.4) as appropriate.
