Numerous more minor changes were also added. Among these were two-dimensional string arrays, as opposed to one-dimensional in the previous version, as well as the ability to use the codice_10 to define string-based functions rather than just mathematical. New system-oriented functions included CLK$, DAT$ to work with times and dates, TIM which returned the elapsed time, and USR$ which returned the user number, what would today be the username. New string functions included LEN, STR$, VAL, ASC, which are common in modern BASIC dialects. The as a short form for codice_14 also appeared in this version.
