sort structure by field
 
Description

L sortf(X, i)
sortf(X, i) produces a sorted list of the values from the record, list or set, X.

List and record values in X are ordered by comparing the values of their ith fields. The value of i can be negative but not zero. Two structure values in X having equal ith fields are ordered as they would be in regular sorting, but structures lacking an ith field appear before structures having them.
 
Parameters
X
list, set or record
i
1 based field number
L
sorted elements of X
 
Defaults
i
1
 
Errors
101 i is not an integer
125 X is not list, set or record
205 i = 0
