System and Other FunctionsNote that the $ZCYC value of an 8-bit string is identical to the $ZCRC mode 1 value.ParametersstringA string. Can be specified as a value, a variable, or an expression. String values are enclosedin quotation marks.ExampleIn this example, the first $ZCYC returns 65; the second returns 3; and the third returns 64.SET x= $ZCYC("A"); 1000001 (only one character; no XOR )SET y= $ZCYC("AB"); 1000001 XOR 1000010 -> 0000011SET z= $ZCYC("ABC"); 1000001 XOR 1000010 -> 0000011 | 1000011 -> 100000WRITE !,"x=",x," y=",y," z=",zSee Also• $ZCRC function$ZFInvokes non-Caché ObjectScript programs or functions from Caché ObjectScript routines.$ZF("function_name",args)Parametersfunction_nameargsThe name of the function you want to call.Optional — A set of argument values passed to the function.DescriptionThe various forms of the $ZF function allow you to invoke non-Caché ObjectScript programs(such as shell or operating system commands) or functions from Caché ObjectScript routines.You can define interfaces or links to functions written in other languages into Caché and callthem from Caché ObjectScript routines using $ZF.$ZF can also be used to:528 Caché ObjectScript Reference
