Hi Tom,

Here's how:
FUNCTION MakeTempFile
PARAMETERS m_Extension
PRIVATE m_TempName
PRIVATE m_Exist
* PRIVATE m_Extension
PRIVATE m_Directory
PRIVATE __Prefix
__Prefix = ".tmp"
m_TempName = ""
m_Exist = .T.

DO WHILE (m_Exist)
m_TempName = alltrim(SYS(3))+__Prefix
IF (!FILE(m_TempName))
m_Exist = .F.
ENDIF
ENDDO

RETURN (m_TempName)
