Each record describing a symbol in the Symbol Table is preceded by a byte containing the value 83 - the ASCII value of "S". The file will contain one of these records for each symbol in the grammar. The Table Count record, which precedes any symbol records, will contain the total number of symbols.
| Item | Type | Description |
|---|---|---|
| Index | Integer | This parameter holds the index of the symbol in the Symbol Table. The symbol should be stored directly at this Index. |
| Name | String | The name of the symbol is stored as a Unicode string. |
| Kind | Integer | This number denotes the kind (or type) of the symbol. The description of each constant is described below: |
| Value | Name | Description |
|---|---|---|
| 0 | Nonterminal | Normal Nonterminal |
| 1 | Terminal | Normal Terminal |
| 2 | Noise | Noise terminal. These are ignored by the parser. Comments and whitespace are considered 'noise'. |
| 3 | End of File | End Character - End of File. This symbol is used to represent the end of the file or the end of the source input. |
| 4 | Group Start | Lexical group start. |
| 5 | Ground End | Lexical group end. Groups can end with normal terminals as well. |
| 6 | Decremented | This was used in the CGT file format. It is not used in EGT. |
