# Arrays and relational expressions

Individual elements of dimensioned and dynamic arrays are
compared in relational expressions using the standard syntax.

## Example(s)

Compares an element in the dimensioned
array `a` to the value `x`. If any element
equals `x`, the `then` command is performed.

```
dim a(10)
if a(element.exp) = "x" then...
```
Checks that an attribute position in the dynamic array `s` is greater-than or equal to `10`.

```
if s<attr.exp> >= "10" then...
```
Checks an element of a dimensioned array `a` for a string in the attribute, value, and subvalue.

```
dim a(10,10)
if a(row.num,col.num)<ac.exp,vc.exp,sc.exp> = "x" then...
```
