where format-specifier specifies an optional printf format specifier, as defined in ISO/IEC 9899 plus the additions shown in Table 49. If a format specifier is not specified, the value’s DISPLAY_FORMAT attribute is used. If a DISPLAY_FORMAT attribute is not specified, a default format is used based on the type of the value, array-index specifies an index in the blk_ids, bik_nums, Ids, and indices array used to specify the value to be embedded in the prompt. local-variable-name specifies the name of the local variable to be embedded in the prompt. The %L form will embed the label of a variable, record member, or array element in the prompt, instead of a value.
The blk_ids parameter specifies the item ids of the blocks to be accessed, while the blk_nums parameter specifies the relative indices of the blocks to be accessed.
If an element of the ids parameter references a variable, the corresponding element of the indices parameter is ignored. If an element of the ids parameter references a record, the corresponding element of the indices parameter specifies a member of the record. If an element of the ids parameter references an array, the corresponding element of the indices parameter specifies an element of the array.
The elements of the blk_ids, ids, and indices parameters are typically specified using the ITEM_ID() and MEMBER_IDO builtin functions. The elements of the blk_nums parameter are typically specified using the get_block_instance_by_object_index() and get_block_instance_by_block_tag() builtin functions.
The bik_ids, blk_nums, and ids parameters may be passed as NULL if there are no values embedded in the prompt. If any of these parameters are passed as NULL, they all shall be passed as NULL.
The indices parameter may be passed as NULL if the ids parameter only references variables, i.e., it does not reference any records or arrays.
The id_count parameter shall be passed as zero if the blk_ids, blk_nums, and ids parameters are passed as NULL.IEC 61804-5-2020 pdf free download.
