Hi Tamar
*speed is important when the string is big and yes in this case it more slow.
But here its a small string and there is no diffrence.
*this is another solution:

local m.accounts,m.x
m.accounts='100,1100,200,250,3000'
m.accounts=strtran(m.accounts,',',chr(13))

m.x=""
for i=1 to memlines(m.accounts)
m.x=m.x+"Accounts["+trans(i)+"]="+mline(m.accounts,i)+chr(13)
endfor
_clipboard=m.x
messagebox(m.x,"string in clipboard")
