Solving IBM Transformation Extender interface problems

There are two ways to solve the problems that occur when interfacing non-IBM Transformation Extender systems a with IBM Transformation Extender systems:

• Create files with a .tmp extension and rename the file when done writing. The IBM Transformation Extender with Launcher ignores any file with a .tmp extension and will process the file after it is renamed. This is the technique used by the IBM Transformation Extender internally, and it is called a "shadow file".
• Create two files: first the actual data file and then a one-byte trigger file. This is a popular option when FTPing into a system running under the Launcher, there has to be a relationship in the file names between the trigger file and the data file, so that the Launcher can derive the name of the data file from the trigger file name. The triggered map has to have the trigger file card before the data file card and the data file card should not be a trigger, only the trigger card should be a trigger.
