===Strings===
Suffixing a variable with {{code|$}} indicated it was a string. String functions include the common {{code|ASC, CHR$, LEN, STR$, VAL}}. The {{code|STRING$}} function makes copies of a given pattern string so that {{code|A${{=}}STRING$(17, "X")}} will produce a string of 17 X's.{{sfn|Manual|p=44}} Only one manipulation function is included, {{code|MID$}}, which works as in MS, but can also be used to replace characters in an existing string, {{code|MID$(A$,1,1){{=}}"Y"}} will replace the first letter of A$ with Y. {{code|INKEY$}} returns the current key pressed on the keyboard, if any.{{sfn|Manual|p=45}} {{code|+}} was used for [[string concatenation]], as in most dialects.

The {{code|HEX$, OCT$ and BIN$}} functions returned a string encoding the value passed in. For instance {{code|PRINT HEX$(255)}} produces FF, while {{code |PRINT BIN$(255)}} produces 0000000011111111.
