ZBasic System Library 199 ZX Microcontroller Family PutNibble Type Subroutine Invocation PutNibble(var, nibbleNumber, val) Parameter Method Type Description var ByRef any type The variable to which the nibble will be written. nibbleNumber ByVal int8/16 The nibble number to write. val ByVal Byte The nibble value. Discussion This routine writes a single nibble (four bits) to memory beginning at the location of the specified variable. Nibble numbers 0-1 are written to the byte at the specified location, nibble numbers 2-3 are written to the subsequent byte, etc. In each case, the lower nibble number corresponds to the least significant four bits of the byte while the higher nibble number corresponds to the most significant four bits of the byte. Only the least significant four bits of the val parameter is used; the remaining bits are ignored. Caution If you specify a nibble number beyond the number of nibbles in the specified variable, a byte in memory following the variable will be modified, perhaps with undesirable results. Compatibility This routine is not available in BasicX compatibility mode. See Also GetNibble
