For()

Iterates through each item in a list, reassigning a given variable to the current item on each iteration. For() is a looping function similar to While() and Repeat(), where the content expression is evaluated each cycle.

result := For( list , varname , content )

list

A comma separated list of items

varname

The name of the variable into which the current list item will be placed during each cycle

content

The expression to be evaluated during each loop cycle

result

A concatenation of the evaluations through every cycle

Concatenates the numeric position of the letter "b" in each of the items within "my_list" to a variable named "test"

my_list := "boat,abacus,rebound";
test := For(my_list, "item",
  Pos("b", item)
);
MessageDlg(test)

Writes a list of names and fully qualified mailbox addresses in the console, one per line, to a file named \database\users.txt

Define("Name", GetSystemVar("/mailslots/" ++ box ++ "/Description"));
a := CreateFile("users.txt");
For(GetMailboxes(), "box",
  If(GetMailboxProp(box, "Type") = "mailbox",
    Write(a, "\q" ++ Name() ++ "\q <" ++ box ++ "@" ++ LOCALHOST ++ ">")
  )
);
CloseFile(a)
