4. Compiler generated names
The symbolic listing will contain many references to names not found in the source language. These compiler generated names have the same form; a two or three letter symbol, followed by a right parenthesis, followed by a number, i.e.:
SYM)NNN
The symbol part, SYM, may be one of the following:
| Symbol | Abbreviation For | |
|---|---|---|
| I. | RS | Result Storage |
| II. | TS | Temporary Storage |
| III. | BL | Base Locator |
| IV. | PI | Positional Indicator |
| V. | CP | Constant Pool |
| VI. | GN | Generated Name |
| VII. | SYS | System Subroutine |
| VIII. | IOC | I/O Subroutine or Communication |
The number NNN specifies a particular item in one of the 8 groups. In the case of constants (CP references), the designation CP)+NN is used.
1. RS - Result Storage
Result Storage cells are reserved by the compiler to temporarily store the results of a CT statement. Unique result storage cells are reserved for each section of the program as they are needed. Examples of instructions which refer to Result Storages might be:
SLW 1.RS)0
LAS 2.RS)2
The number preceding the decimal point is a section-number and the number following the right parenthesis is a particular result storage within the section. Section numbers begin with 0 (main body of program) and increase by 1 for each 'Begin Section' in the source program. Near the end of the symbolic listing (after the last instruction generated by the Procedure Division) the following instructions will appear:
USE 1
RS) BSS N(Omitted if no Result Storages are required)
These instructions reserve the necessary cells for all Result Storage. N is the sum of maximum Result Storage used in each section.
