Caché ObjectScript FunctionsNote:The $BIT functions replace the earlier $ZBIT functions. New code should only usethe $BIT functions; the $ZBIT functions will continue to be supported for legacyapplications. The $BIT functions and the $ZBIT functions are incompatible; $BITfunctions compress bitstrings, $ZBIT functions do not. Therefore, the two types ofbitstring functions should not be used on the same bitstring.See Also• $BITCOUNT function• $BITFIND function• $BITLOGIC function• $FACTOR function$BITCOUNTReturns the number of bits in a bitstring.$BITCOUNT(bitstring,bitvalue)ParametersbitstringbitvalueThe name of a bitstring. Can be a local variable, a process-privateglobal, or a global.Optional — The value (0 or 1) to count within the bitstring.DescriptionThe $BITCOUNT function counts the number of bits within a bitstring. A bitstring is a stringwhich is interpreted by the system as a series of bits. You can create a bitstring using $BITor $BITLOGIC. There is also general information on bitstring functions available.$BITCOUNT(bitstring) returns the number of bits in bitstring.$BITCOUNT(bitstring, bitvalue) returns the number of bits of type bitvalue (0 or 1) inbitstring.The maximum bitstring length is 262,104 bits (32763 x 8).184 Caché ObjectScript Reference
ExamplesIf bitstring= [0,0,1,1,0], then the result of $BITCOUNT(bitstring) is 5:$BITCOUNTSET $BIT(a,1) = 0SET $BIT(a,2) = 0SET $BIT(a,3) = 1SET $BIT(a,4) = 1SET $BIT(a,5) = 0WRITE !,$BITCOUNT(a)If bitstring = [0,0,1,1,0], then the result of $BITCOUNT(bitstring,0) would be 3.SET $BIT(a,1) = 0SET $BIT(a,2) = 0SET $BIT(a,3) = 1SET $BIT(a,4) = 1SET $BIT(a,5) = 0WRITE !,"number of zero bits:",$BITCOUNT(a,0)WRITE !,"number of one bits: ",$BITCOUNT(a,1)See Also• $BIT function• $BITFIND function• $BITLOGIC function• $FACTOR functionCaché ObjectScript Reference 185
