Creates a list from a string.
||A string to be converted into a Caché list. This string contains one or more elements, separated by a delimiter. The delimiter does not become part of the resulting Caché list.
||Optional The delimiter used to separate substrings (elements) in string. Specify delimiter as a quoted string. If no delimiter is specified, the default is the comma (,) character.
takes a quoted string containing delimited elements and returns a list. A list represents data in an encoded format which does not use delimiter characters. Thus a list can contain all possible characters, and is ideally suited for bitstring data. Lists are handled using the ObjectScript $LIST
A string literal (enclosed in quotation marks), a numeric, or a variable or expression that evaluates to a string. This string can contain one or more substrings (elements), separated by a delimiter
. The string data elements must not contain the delimiter
character (or string), because the delimiter
character is not included in the output list.
A character (or string of characters) used to delimit substrings within the input string. It can be a numeric or string literal (enclosed in quotation marks), the name of a variable, or an expression that evaluates to a string.
Commonly, a delimiter is a designated character which is never used within string data, but is set aside solely for use as a delimiter separating substrings. A delimiter can also be a multi-character string, the individual characters of which can be used within string data.
If you specify no delimiter, the default delimiter is the comma (,) character. You cannot specify a null string ("") as a delimiter; attempting to do so results in a <STRINGSTACK> error.
The following example takes a string of names which are separated by a blank space, and creates a list:
SET namestring="Deborah Noah Martha Bowie"
SET namelist=$LISTFROMSTRING(namestring," ")
WRITE !,"1st element: ",$LIST(namelist,1)
WRITE !,"2nd element: ",$LIST(namelist,2)
WRITE !,"3rd element: ",$LIST(namelist,3)
