RE: Variable length array and Split

Having to preprocess the array to add data between delimiters seems to remove the value of %split() function.

Subject: Re: Variable length array and Split

This (coding wise) is off the top of my head with no testing so ....

Variable length arrays are cleared (or set to any size) via %elem - so:

%elem(Dynarray) = 0;

Using Clear I would expect to simply set all currently active elements to their default values.

%Split is documented as ignoring consecutive delimiters. I wish it wasn't so but that is by design apparently.

Only way to make it work is to pre-process the string to insert a non-delimiter character between them.

Well I guess there are other ways as well but ...

Hello sages

Having found a perfect case for splitting a string into a Variable
length array I promptly coded :

dcs-l DynArray char(20) dim(*auto:50) followed by

c clear DynArray
DynArray = %split(string : '|') ;

only to find that
a. clear does not clear a Variable length array b. %split fail to deal
with consecutive delimiters like in "first|second|third||fifth"
(it missed the missing forth element)

What am I doing wrong?

Any advice will be thankfully received.
