**POPBIND**

{{blk2blue.jpg|blk2blue.jpg}}

The **POPBIND** statement restores the previous BIND statement's //name// space for variables and procedures previously bound. This restores the previous scope used by previous BIND statements.

**Example:**

**SomeProc PROCEDURE**

**OrderNumber  LONG**

**Item         LONG**

**Quantity     SHORT**

** CODE**

** BIND('OrderNumber',OrderNumber)**

** BIND('Item',Item)**

** BIND('Quantity',Quantity)**

** AnotherProc                      !Call another procedure**

** UNBIND('OrderNumber',OrderNumber)**

** UNBIND('Item',Item)**

** UNBIND('Quantity',Quantity)**

**AnotherProc PROCEDURE**

**OrderNumber  LONG**

**Item         LONG**

**Quantity     SHORT**

** CODE**

** PUSHBIND                         !Create new scope for BIND**

** BIND('OrderNumber',OrderNumber)  !Bind variables with same names in new scope**

** BIND('Item',Item)**

** BIND('Quantity',Quantity)**

** !Do some Processing**

** UNBIND('OrderNumber')**

** UNBIND('Item')**

** UNBIND('Quantity')**

** POPBIND                          !Restore previous scope for BIND**
