Sorting an array in Sage X3

SORTA NUMVALUE_ToORDER ARRAY [Desc]

SORTA NUMVALUE_ToORDER ARRAY1, array2 [Desc] (array2 ordered following the order of ARRAY1)

Example:

Local Char STR(255)(0..4)
Local Integer NUMBER(0..4)
Local Integer D

NUMBER(0) = 3
NUMBER(1) = 4
NUMBER(2) = 9
NUMBER(3) = 5
NUMBER(4) = 8

STR(0) = "B"
STR(1) = "E"
STR(2) = "C"
STR(3) = "M"
STR(4) = "A"

D= dim(NUMBER)

To sort NUMBER in ascending order, and strings based on NUMBER numbers

Sorta D NUMBER,STR

#final results:

NUMBER(0) = 3
NUMBER(1) = 4
NUMBER(2) = 5
NUMBER(3) = 8
NUMBER(4) = 9

STR(0) = "B"
STR(1) = "E"
STR(2) = "M"
STR(3) = "A"
STR(4) = "C"

To sort the first 4 strings in alphabetical order

Sorta 4 STR

To sort the first 4 strings in alphabetical order, and the numbers based on string order

Sorta 4 STR,NUMBER

To sort in descending order

Sorta D STR, NUMBER  Desc
