FidoNet control paragraphs (a.k.a. “kludge lines”) are how extensible message metadata is shared among FidoNet nodes.
Synchronet and SBBSecho have extended FidoNet messages with the following control paragraphs:
| Control Tag | Description |
|---|---|
| FORMAT: fmt | Indicate if the message text was pre-formatted (FORMAT: fixed) or intended to be line/word-wrapped when viewed, potentially with markup codes parsed and applied to the output (FORMAT: flowed, the default) |
| COLS: n | Specified width (positive decimal number, in columns) of message author's editor or terminal; potentially useful when re-flowing/wrapping message text for display |
| BBSID: id | QWK BBS ID (1-8 alphanumeric characters) of originating BBS, when applicable; for routed QWKnet messages, the BBS ID may be prepended with slash-separated hop-IDs (e.g. “hub-id/bbs-id”) |
| NOTE: info | Message text editor name and version information (not originated by Synchronet/SBBSecho) |
