Purpose
Change the top boundary for scoping key values in the controlling order.
Syntax
SET SCOPE TO [<uNewTop> [, <uNewBottom>]]
Arguments
| <uNewTop> | The top range of key values that will be included in the controlling order's current scope. <uNewTop> can be an expression that matches the data type of the key expression in the controlling order or a code block that returns the correct data type. |
| <uNewBottom> | The bottom range of key values that will be included in the controlling order's current scope. <uNewBottom> can be an expression that matches the data type of the key expression in the controlling order or a code block that returns the correct data type. |
| Note: If <uNewBottom> is not specified, <uNewTop> is taken for both the top and bottom range values. |
Description
SET SCOPE, when used with no arguments, clears the top and bottom scopes; this is equivalent to OrdScope(0, NIL) followed by OrdScope(1, NIL). If <uNewTop> is specified alone, SET SCOPE sets the top and bottom scope to the indicated value (that is, OrdScope(0, <uNewTop>) followed by OrdScope(1, <uNewTop>). If both <uNewTop> and <uNewBottom> are specified, SET SCOPE sets the top and bottom scope as indicated (that is, OrdScope(0, <uNewTop>) followed by OrdScope(1, <uNewBottom>)..
