Help with custom function

johnmoore

hash = Function( {StringList},
	{StringListItem,HashString},
	For( StringListItem = 1, StringListItem <= Length( StringList ), StringListItem++,
		StringList[StringListItem] = Char( Eval( Stringlist[StringListItem] ) )
	);
	HashString = Hex( Blob MD5( Char To Blob( Concat Items( StringList ) ) ) );
);

This is a hash function that I use to create unique ID's.  The function currently takes a list as it's argument.  I would to have it take one or more arguments separated by commas.  I am hoping to add it to custom functions and make it available to other users.  Thought that would be easier for users if it accepted multiple arguments separated by commas like the Sum() function.

 

Any thoughts?

 

Many thanks,

 

John

Here is a method using your code that would allow for the entry of some large preset maximum, but variable list of input parameters for your hash function

hash = Function( {a, b = "", c = "", d = ""}, // e="",f=""...…...z="")
	//{StringListItem,HashString},
	StringList = {};
	string# = 1;
	varList = {"a", "b", "c", "d"}; // .........."z"
	
	While( Eval( Parse( varlist[string#] ) ) != "",
		Insert Into( stringList, Eval( Parse( varlist[string#] ) ) );
		string# = string# + 1;
	);
	For( StringListItem = 1, StringListItem <= Length( StringList ), StringListItem++,
		StringList[StringListItem] = Char( Eval( Stringlist[StringListItem] ) )
	);
	HashString = Hex( Blob MD5( Char To Blob( Concat Items( StringList ) ) ) );
);
