SAL recognizes pretty much the standard assortment of logical operators:
| OPERATOR | SIGN | DESCRIPTION |
|---|---|---|
| Equal | == | Is the value of left side equal to the value of right side? Should not be confused with the assignment operator = |
| Not equal | != | Is the value of the left side different from the value of the right side? |
| Bigger | > | Is the value of the left side bigger than the value of the right side? Does NOT work for comparing strings. |
| Smaller | < | Is the value of the left side smaller than the value of the right side? Does NOT work for comparing strings. |
| Smaller or equal | <= | Is the value of the left side smaller than or equal to the value of the right side? Does NOT work for comparing strings. |
| Bigger or equal | >= | Is the value of the left side bigger than or equal to the value of the right side? Does NOT work for comparing strings. |
| AND | && | Used to connect two variable checks. Both must be true for "AND" to be true. Only two checks can be connected in the same line. |
