Record Declaration

The syntax of an IN external format is declared as follows:

external <format_name> inw { <field declarations> };

No size declarations are necessary for an IN record since it is given by the enclosing sequential record. In fact, an INW record can only be used as the final field in a sequential record.

Field Declaration

The syntax of an IN field is declared as follows:

bcd tag_id(<int_constant>) <field_name> <: options>;

The available tag_id values are given by the Ericsson IN documentation.

The available options are:
