Introduction

Within an OTX document, the references to other OTX documents, which are called as imports in OTX, may be defined. With the aid of the references, global names from other OTX documents can be imported into the current document. The following global names can then be accessed within the current document:

• Signa­tu­res
• Validities
• Global constants
• Context variables
• State variables
• Pro­cedures

Important: All objects above of the imported documents can only be accessed according to their Visibility!

Semantics

• Packa­ge (required)

• Docu­ment (required)
  Contains the name of the document to be imported OTX.
• Pre­fix (required)
  Free name that identifies the imported document. It is represented in all accesses to the imported document.
