NimbostratusIs lindex deprecated?
I cannot find a reference to lindex in https://devcentral.f5.com/wiki/iRules.Functions.ashx. Is lindex deprecated in favor of getfield? Or does this document only cover functions specific to the F5 LTM version of tcl, as lindex is a tcl builtin.

are different function of tcl and can be used in different situation.getfield-
lindex: command treats list as a Tcl list and returns the index'th element from it (0 refers to the first element of the list). In extracting the element, lindex observes the same rules concerning braces and quotes and backslashes as the Tcl command interpreter; If index is negative or greater than or equal to the number of elements in value, then an empty string is returned.

getfield Splits a string on a character or string, and returns the string corresponding to the specific field. The field_number parameter is 1 indexed.
