Summary

REP004 - System and Multilingual Variables

Important Observations

• System variables can be used throughout the repository as default values, in validation rules, etc.

• LANSA ships many default system variables. You can also define your own system variables.

• System variables are NOT partition specific and changing or deleting a system variable affects all partitions in that installation of LANSA.

• Dynamic system variables can have different values each time the variable is accessed.

• Static variables are assigned once when the application is started.

• System variables call a program which returns a single value.

• Multilingual data is stored as keyed data and is not translated.

• All multilingual variables must begin with *MTXT.

Tips and Techniques

• When defining a new partition (or modifying an existing partition) to support multilingual applications, a "default" language and one other language must be defined. A multilingual partition must have two or more languages defined.
