OWN Variables

---------------------------------------------------------------------------------------------
| | |
| SPL | HP C/XL Equivalent |
| | |
---------------------------------------------------------------------------------------------
| | |
| Standard variables declared local to a | Same as SPL, using auto variables (the |
| procedure are assigned new space each time | default). |
| a procedure is invoked, the space being | |
| released when the procedure is exited. | |
| | |
---------------------------------------------------------------------------------------------
| | |
| If a variable is declared as OWN, space is | Same as SPL, using static variables. |
| allocated outside of the dynamic scope of | |
| the procedure, in the DB-relative area. | |
| | |
| The variable is still known only to the | |
| procedure, and it retains its value between | |
| successive calls to the procedure. If an | |
| OWN variable is initialized, it is | |
| initialized once, at the start of the | |
| program, not every time the procedure is | |
| called. | |
