This is a function that I created for a program and I thought I would share. It locates items in an ini file when not all of the info is known.

Take the following for example:

[user_000]
name=Mr. Foo
email=MF1245@me.com

[user_001]
Name=John Pocket
email=Mr.JP@me.com

This file was generated by an online company. One section per user with info. I know the user's email address but not the name and the section (user number).

I would use my function to find the section the email address is in then I can find the user's name.

%t = @FindInINI(@path(%0)MyIni.ini,,,MF1245@me.com)

This would return User_000|email.... <Section>|<Key>
I can parse it to get the section and then use @iniread(User_000,name) to get the user's name.

Anyway, here is the code.

Code:

:FindInINI
  #%a = @FindInINI(<FileName>,<Section Name>,<Key Name>,<Value>[,<Optional Result S = Section, K = Key, Default is both>)
  #this will close any previously opened ini file and open the file provided.
  #this is used to find a Key or Value in an ini file.
  #if a Section and key are used. The value is returned just like @iniread(section,key)
  #if only a Section and value is used, that whole section is searched and
  #returns the KEY name it was found under.
  #if no Section supplied then the whole file is searched.
  #if a key name is supplied, the file is searched for the first matching
  #key and returns Section|value
  #if only the value is supplied then the whole file is searched and returns Section|key
  if @not(%1)
    error 2
  end
  if @not(%3)
    if @not(%4)
      error 2
    end
  end
  inifile open,%1
  %%find_in = @new(list)
  if %2
    list assign,%%Find_in,@iniread(%2)
    if @not(@text(%%Find_in))
      %%find_exit =
    end
    if %3
      %%find_exit = @iniread(%2,%3)
    elsif %4
      %x = 0
      repeat
        %i = @item(%%Find_In,%x)
        if @greater(@pos("=",%i),0)
          %%find_key = @trim(@substr(%i,1,@pred(@pos("=",%i))))
          %%find_value = @trim(@substr(%i,@succ(@pos("=",%i)),@len(%i)))

            %%find_exit = %%Find_Key
