The FM line is limited to how many characters?

• A. 60
• B. 69
• C. 72
• D. 80

Answer: (B)

The FM line length is sixty-nine characters. This limit comes from fixed‑width messaging practices used on older equipment, where a single line needed to fit cleanly on most displays and printers without wrapping. Keeping to sixty-nine characters ensures the entire line prints or transmits as a unit, which reduces the chance of misinterpretation and makes automated processing straightforward. If you push beyond this limit, the line is at risk of wrapping or being truncated on some systems, which can create confusion or require splitting the line into additional lines with continuation indicators. The smaller limit would unnecessarily constrain information, while larger limits exceed what the common equipment reliably handles, increasing the chance of truncation or wrap.
