String variables are represented by any variable with the suffix $, e.g. C$ or MYVAR$. They are stored as null-terminated C-style sequences of 8-bit ASCII characters.

Examples

name$ = "Retro Rocket"

PRINT "Hello, "; name$

REM Concatenate strings
first$ = "Hello"
second$ = "World"
PRINT first$ + " " + second$

REM Accessing characters
ch$ = LEFT$(name$, 1)
PRINT "First character = "; ch$

Notes

Strings are mutable and can be reassigned at any time.
Maximum length depends on available memory.
Operations such as concatenation (+), substring (LEFT$ / RIGHT$ / MID$), and trimming (TRIM$) are supported.
Null termination is internal — it is not visible during normal BASIC operations.
