| function | usage | example |
| size | This function return the number of item that are stored into a list. | { 1 2 "aaa" } gives 3 |
| list-> | Explode the list. put into stack each item of the list and give the number. (into a list) |
{ 1 2 "aaa" } gives on stack
1
2
"aaa"
{ 3 }1, 2, and "aaa" are items, and { 3 } is the number of item |
| ->list | build a list, need the number of item to store at first information (TOS). | the stack has :
"abc" 123 2we execture ->list it gives : { "abc" 123 }Please note that the number of item can be given in numerical 2 or in a list { 2 }.
|
| reverse | move item inside the list to perform a reversal | { 1 2 "aaa" } gives {"aaa" 2 1} |
| sort | sort the content of the list. works for number and string |
{ 5 "aa" 3 "bb" 6 } gives
{3 5 6 "aa" "bb"}
|
| add | add an item to the end of the list or concatenate two lists |
{ 1 2 } 3 add gives {1 2 3}{1 2} {3 4} add gives {1 2 3 4} |
| get | Extract objects from a list works also for strings and array |
{"a" "b" "c" "d" "e"} 2 get gives { "b" }{"a" "b" "c" "d" "e"} { 2 4 } get gives { "b" "c" "d" } ( from 2 to 4 ) |
| sum | compute the sum of all item of a list | { 1 2 3 } sum gives 6{ "aa" "b" "c" } sum gives "aabc" |
| len | give a list of lenght of each item. warning : this is not size |
{ "aa" "bbb" } len gives {2 3}it consider each item as string for computing len : { 1 1.5 "a" } len gives { 1 3 1 }
|
| min | gives a min value of a numerical list | {8 2 6} min gives 2 |
| max | gives a max value of a numerical list | {8 2 6} min gives 8 |
| chr | Convert a list of interger/hex into a string - this is the reversal of ASC. the list contains the ascii code |
{65 66} chr gives "AB"{0x41 0x42} chr gives "AB"note that 65 is equal to 0x41 in hexadecimal base. |
| asc | give all ascii code of a string into a list |
"A1" asc gives {0x41 0x31}it works also for lists : { "A" 1 } asc gives {0x41 0x31}as you see 1 have been translated into string and then asc gives the ascii value 0x31 (49) |
| {}->[] | convert a list into an array (matrix/vector) in fact it also convert inner lists (see 2nd example) |
{1 2} {}->[] gives [ 1 2 ] (an array){{1 2}{3 4}} {}->[] gives [[1 2][3 4]] (a matrix)even if it's just a part, it convert it : {[1 2]{3 4}} {}->[] gives [[1 2][3 4]] (a matrix)
|
| min | gives the lowest numerical value | { 1 2 3 } min gives 1
|
| max | gives the highest numerical value | { 1 2 3 } min gives 3
|
| {}->poly | Create a polymial | {5 6 7} {}->poly gives 5 + 6x + 7x² |
| head | get the first object of a list | { 1 2 3 } head gives 1{ {1 "a"} 2 3} head gives {1 "a"}
|
| concat | concatenate each list item and add separators | { 1 2 3 } "x" concat gives "1x2x3"{1 2 "z"} ";" concat gives "1;2;z"
|
| ForEach | to perform a program (see example) on each item of a list. note : QLE script are also allowed |
{1 2 3} « ^2 » gives {1 4 9} |
| List->Script | Convert a list into a StringSource for scriptig see Quick List Entry |
{1 DUp} List->Script gives "1 \! DUP" |
{ 2 3 4 } ^2, gives { 4 9 16 }
