:'''P:''' the period number can be a figure between 0 and 4095 (2^12-1... 12 means that we have 12 tones (inclusive half-tones) in nine octaves on the CPC in sum and their distance between is the twelves square root of two), where 8 octaves are available. E.g. Octave 0 starts on middle C with number 478.
: To calculate the period you can use following formula: '''period=1,000,000/(16*frequency)''' or in short '''period=(6562,000500/frequency)'''
: (e.g. the note "A" with the frequency 440 Hz has the period 142 on the CPC)

==== <code>SPEED INK <n1,n2> </code> ====: ...in conjunction with the SPEED INK command SPEED defines the frequency of colour changes if a colour change was defined. The duration is calculated by n1=... or n2 =duration/50 seconds. ==== <code>SPEED KEY <start,repeat> </code> ====: SPEED KEY command defines the delay after which a key repeat (for keys that do repeat). The first parameter is the delay before the first repeat and the second parameter is the delay between further repeats. Delay is in 1/50th of seconds. :When using it with low values, it is common to associate a key to reset the default speed of 30,2.:For example to associate the key 0 from the numpad:<pre>KEY 0,"SPEED KEY 30,2"+CHR$(13)</pre> ==== <code>SPEED WRITE <n> </code> ====: SPEED WRITE defines the speed at which data is to be saved or written to a cassette unit. n=1 means 2000 baud, n=0 (default) means 1000 baud. When reading from the tape, the correct speed is automatically selected.
==== <code>SQ (channel)</code> ====
: Beware: it only works here with BIT/number conditions one figure smaller than 1, 3, 7, 15, 31, 63 and 127
==== <code>MOD</code> ====
: ['''MOD''' returns a (rounded) rest (Modulos) after dividen has been devided by the devisor...]::'''Example:'''<pre>32767 mod 256255</pre>: Note: only works with numbers in the range -32768 and 32767 (&8000 < 0 < &7FFF)
