Add lists to a master list

RVERP

Hi, i want to add a list to a 'master' list.  I want to use to cons function for this.

masterList = cons(list_3 masterList)

 This works, no problem, only the number of the list to be added is determened by the i in a for loop.

 for( i 1 20
masterList = cons( "list_i" masterList))

  I don't know what function to use that gives the correct return for "list_i"

    Hi,

    cons function adds a “element” to beginning of a list. If you want to merge two lists, try using append/append1

    Also take out “list_i” from your code as this is considered as a string and hence it will not work and will not put a new incremented value of “i” inside your for loop. Assign the value to the new item immediately after the for loop and then use your function to combine list/items.
