| LBOUND Function Details |
|
| Syntax |
| LBOUND(array[,dimension]) |
| |
| The LBOUND function is used with the UBOUND function to determine the |
| size of an array. |
| |
| Argument Description |
| array The name of the array being dimensioned |
| |
| dimension An integer ranging from 1 to the number of dimensions |
| in array: indicates which dimension's lower bound is |
| returned |
| |
| For an array dimensioned as follows, LBOUND returns the values listed below: |
| |
| DIM A(1 TO 100, 0 TO 50, -3 TO 4) |
| |
| Invocation Value Returned |
| LBOUND(A,1) 1 |
| LBOUND(A,2) 0 |
| LBOUND(A,3) -3 |
| |
| The default lower bound for any dimension is either 0 or 1, depending |
| on the setting of the OPTION BASE statement. If OPTION BASE is 0, the |
| default lower bound is 0, and if OPTION BASE is 1, the default lower |
| bound is 1. |
| |
| Arrays dimensioned using the TO clause in the DIM statement may have any |
| integer value as a lower bound. |
| |
| You may use the shortened syntax LBOUND(array) for one-dimensional arrays, |
| since the default value for dimension is 1. Use the UBOUND function to find |
| the upper limit of an array dimension. |
