=== {{header|ZX Spectrum Basic}} ===
The ZX Spectrum uses single letter variables names. None of these are special variables. There are a set of system variables held at a fixed memory addresses, which can be accessed via PEEK and POKE functions:
<lang zxbasic>10 PRINT "The border colour is "; PEEK (23624): REM bordcr
20 PRINT "The ramtop address is "; PEEK (23730) + 256 * PEEK (23731): REM ramtop
30 POKE 23609,50: REM set keyboard pip to 50</lang>
