In Analysis and Aggregation agents, module names are not needed if the format is selected in the UDR Types list in the configuration dialog of the agent. Also, the APL Editor allows selection of the UDR types from a list. Right-click in the Code Area to display the UDR Assistance... via which the UDR Internal Format Browser can be opened.

If none of these lists are used, the full format name must be referred to, or the import keyword must be used. The module name must be prefixed with ultra.to distinguish format imports from APL code imports.

import ultra.Default.CDR;
  
 CDR_TI newUDR() { 
    CDR_TI myUDR = udrCreate( CDR_TI ); 
    myUDR.field1 = 22; 
    myUDR.field2 = 55; 
    return myUDR; 
 }

Default.CDR.CDR_TI newUDR() { 
    Default.CDR.CDR_TI myUDR = udrCreate( Default.CDR.CDR_TI ); 
    myUDR.field1 = 22; 
    myUDR.field2 = 55; 
    return myUDR; 
 }

It is possible to split different blocks of a format between several format definitions. In these cases, the import statement may be used to avoid referring to the module name. The ultra. prefix is not needed (or allowed) in the UFDL import statement.

Using import in UFDL Code

Suppose there is a format definition with the module name Default.AMA containing an internal myInt, and a new format definition must include the internal in the in_map. This can be accomplished in two ways:

Case 1 - import

import Default.AMA;
in_map exMap : external( myCDR ), 
               internal( myInt ),
               target_internal( myCDR_TI ) {
                 automatic;
};

Case 2 - no import

in_map exMap : external( myCDR ), 
               internal( Default.AMA.myInt ), 
               target_internal( myCDR_TI ) { 
                 automatic; 
};

asn_block {
  exchangeRec DEFINITIONS IMPLICIT TAGS ::= 
    BEGIN
      main_udr ::= SEQUENCE
      // Field specifications
};

import Default.myASNformat.exchangeRec;

in_map exMap : external( main_udr ),
               internal( myInt ),  
               target_internal( myCDR_TI ) {
                 automatic;
}; 

in_map exMap : external( Default.myASNformat.
                         exchangeRec.main_udr ),
               internal( myInt ),
               target_internal( myCDR_TI ) {
                 automatic;
};
