Description
The CREATE FROM command creates a new table, determined by the contents of a table created with the COPY STRUCTURE EXTENDED command. The filenames can be substituted with a <expC1>, enclosed in round brackets, which returns a valid filename. The FROM table consists of five fields, these are:
| Field | Type | Width | Description |
|---|---|---|---|
| FIELD_NAME | Character | 32 | Field name |
| FIELD_TYPE | Character | 1 | Data type of field |
| FIELD_LEN | Numeric | 3 | Width of field |
| FIELD_DEC | Numeric | 3 | Number of decimal places |
| FIELD_DES | Character | 25 | Field Description |
Each record of the FROM table defines a field. The structure of the new table, <filename1>, will be created from these field definitions.
