==== <code><big>PEEK (add<address expression>)</big></code> ====: ''BASIC 1.0 & 1.1'': '''FUNCTION''': Reports the contents of the Z80 memory location specified in the <address expression> which should be in the range &0000 to &FFFF (0 to 65535). In all cases PEEK will return the value at the RAM address specified (not the ROM), and will be in the range &00 to &FF (0 to 255)

==== <code><big>POS (#<stream expression>)</big></code> ====
: ''BASIC 1.0 & 1.1''
: '''FUNCTION''': Reports the current horizontal POSition of the text cursor relative to the left edge of the text window. The <stream expression> MUST be specified, and does NOT default to #0.
: POS(#8) reports the current horizontal carriage position for the printer, where 1 is the extreme left hand edge.
: POS(#9) reports the logical position in the disc file stream, i.e. the number of printing characters sent to the stream since the last carriage return.
