Usage notes
Every SOUL request must be preceded by either the Begin or More command and must be concluded by an End statement. After encountering a Begin command, Model 204 assumes that every user input line is a SOUL statement (or a portion of a statement), until the End statement is processed.
Output from a SOUL request appears on the user's terminal unless a USE command directs the output to an alternate device.
A Begin command is required even when a request is embedded in a stored procedure. SOUL requests are described in detail in the SOUL wiki pages.
When Begin follows another command that does not automatically end its own update unit (for example, DEFINE FIELD), Model 204 ends any update unit in progress and begins a non-backoutable update unit.
