' This is the delimiter character
VAR.$$DEL=;
' This is the Line that has delimited items
VAR.$$LIN=AA;BB;CC;DD;EE;FF
' This is the Index-List with the Elements where we want to insert new fiels before
VAR.$$IND="A","E",3
' Now we call the command
DIC.remove|$$DEL|$$LIN|$$IND|$$RES
' And Debug-Print the Result
DBP.$$RES
ENR
And this is the result: BB;DD;FF
