This code creates a random string of letters. Good for creating random file names.

Useage: @RandomName(<Number of chars>)
Default is 4 id <Number of Chars> is left blank.

Code:

#Define function,RandomName
:RandomName
  #%1 = num of chars, blank for default of 4
  %c = "abcdefghijklmnopqrstuvwxyz"
  if @not(%1)
     %1 = 4
  end
  RANDOM @datetime(shn)
    %i = 1
    repeat
      %p = %p@substr(%c,@random(1,@len(%c)))
      %i = @succ(%i)
    until @equal(%i,@succ(%1))
  exit @upper(%p)

Hi LiquidCode:

Very useful code. It can add an formatting argument, this way:

Code:
  #Define function,RandomName
:RandomName
  #%1 = num of chars, blank for default of 4
  #%2 = format string where N=number and L=letter; letter for default
  %c = "abcdefghijklmnopqrstuvwxyz"
  if @not(%1)
     %1 = 4
  end

  RANDOM @datetime(shn)
  %i = 1
  if @greater(%1,@len(%2))
    %2 = %2@fill(@diff(%1,@len(%2)),L)
  end
   
  repeat
    if @equal(@substr(%2,%i),N)
      %p = %p@random(0,9)
    else
      %p = %p@substr(%c,@random(1,@len(%c)))
    end
 
    %i = @succ(%i)
  until @equal(%i,@succ(%1))
exit @upper(%p)


We can define the format of the string:

Code:
%a = @randomname(8,NNLLLLLL)

Option for either <Length> or <Format String> and added characters:
*Edited to remove invalid filename characters.
Code:

#Define function,RandomName

info @RandomName(6)
info @RandomName(NNLLNNCCC)

exit

:RandomName
  #%1 = num of chars, blank for default of 4 or format string where N=number and L=letter; letter for default
  %c = "abcdefghijklmnopqrstuvwxyz"
  %d = "~!@#$%^&()_+`-={}[];',."
  if @not(%1)
     %1 = 4
  end

  RANDOM @datetime(shn)
  %i = 1
  if @not(@numeric(%1))
    %2 = %1
    %1 = @len(%1)
  end
   
  repeat
    if @equal(@substr(%2,%i),N)
      %p = %p@random(0,9)
    else
      if @equal(@substr(%2,%i),C)
        %p = %p@substr(%d,@random(1,@len(%d)))
      else
        %p = %p@substr(%c,@random(1,@len(%c)))
      end
    end

If it wants to generate a consistent string as a valid file name, it must eliminate some characters:

Code:
%d = "~!@#$%^&()_+`-={}[];',."

I revisited this code. I needed to generate many random names in more than a second and since the seed is based on the time it only changes every second. So I take it farther and also add a Random_Seed variable that is generated from the previous seed. So in theory, no two names should be the same when generated in less than a second.

Code:

#Define function,RandomName

#info @RandomName(6)
list create,1
%x = 0
repeat
     list add,1,@RandomName(NNLLNN)
     %x = @succ(%x)
until @equal(%x,10)
info @text(1)
exit

:RandomName
  #%1 = num of chars, blank for default of 4 or format string where N=number and L=letter; letter for default
  %c = "abcdefghijklmnopqrstuvwxyz"
  %d = "~!@#$%^&()_+`-={}[];',."
  if @not(%1)
     %1 = 4
  end
  if %%Random_seed
     Random %%Random_Seed
  else
     RANDOM @datetime(shn)@random(0,9)
  end
  %i = 1
  if @not(@numeric(%1))
    %2 = %1
    %1 = @len(%1)
  end

  repeat
    if @equal(@substr(%2,%i),N)
      %p = %p@random(0,9)
    else
      if @equal(@substr(%2,%i),C)
        %p = %p@substr(%d,@random(1,@len(%d)))
      else
        %p = %p@substr(%c,@random(1,@len(%c)))
      end
    end
    %i = @succ(%i)
  until @equal(%i,%1)
  %%Random_Seed = @random(1000)
 exit @upper(%p)
