Sort - Function Summary


Sorts a series.


sort series


series - The series argument. (must be: series port)


/case - Case sensitive sort.

/skip - Treat the series as records of fixed size.

size - Size of each record. (must be: integer)

/compare - Comparator offset, block or function.

comparator - The comparator argument. (must be: integer block function)

/part - Sort only part of a series.

length - Length of series to sort. (must be: integer)

/all - Compare all fields

/reverse - Reverse sort order


If you are sorting records of a fixed size, you will need to use the /SKIP refinement to specify how many elements to ignore.

Normally sorting is not sensitive to character cases, but you can make it sensitive with the /CASE refinement.

A /COMPARE function can be specified to perform the comparison. This allows you to change the ordering of the SORT.

Sorting will modify the series passed as the argument.

    blk: [799 34 12 934 -24 0]
    print sort blk
    -24 0 12 34 799 934

    names: ["Fred" "fred" "FRED"]
    print sort/case names
    FRED Fred fred

    name-ages: [
        "Larry" 45
        "Curly" 50
        "Mo" 42
    print sort/skip name-ages 2
    Curly 50 Larry 45 Mo 42

    names: [
    print sort/compare names func [a b] [a < b]
    Curly Larry Mo

    print sort "edcba"

The ALL refinement will force the entire record to be passed to the compare function. This is useful if you need to compare one or more fields of a record while also doing a skip operation.


append - Appends a value to the tail of a series and returns the series head.
change - Changes a value in a series and returns the series after the change.
clear - Removes all values from the current index to the tail. Returns at tail.
insert - Inserts a value into a series and returns the series after the insert.
remove - Removes value(s) from a series and returns after the remove.
