- | * Static. | + | |
- | * indexed. | + | |
- | + | ||
- | Static variables can take on different values according to their program (column) reference. In the declaration each of these variables is identified by an individual name so, to be able to refer to different values that it can take on, indexing has to be used. For example, to refer to the //dslVeMa// variable of program (column) 5, use the code: | + | |

+ | * In a DATAGROUP all variables, both static and indexed, are retentive (maintain the value at power off). | ||
+ | * The Datagroup variables may be more than one, in this case it is necessary to insert more DATAGROUP keywords. | ||
+ | * The subsection DATAPROGRAM is mandatory, while the STEP is optional. | ||
+ | * The maximum number of recipes can be set is 65534. | ||
+ | * The maximum number of steps can be set is 65534. | ||
+ | * Compared to a common array, static variables can also support a Flag size data (F). | ||
