External - Ericsson IOG/IN Records

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. 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:

Option	Description

Option	Description
`num_frame`	Indicates that the field has a number frame. Two fields are generated if this is specified, one with the specified field name and the other suffixed with `_NumFrame`.
`gnci`	Indicates that the field has a GNCI. Two fields are generated if this is specified, one with the specified field name and one suffixed with `_GNCI`.
`gnci on (<expr>)`	As `gnci`, however, the GNCI is only present if the expression is evaluated to `true`.
`terminated_by(<expr>)`	Identical to sequential definitions.
`int(base10)`	Identical to sequential definitions.
`int(base16)`	Identical to sequential definitions.
