The Concatenate process accepts two strings or numbers as input, one called “Base” and one called “Suffix”. It then outputs a string consisting of “Base” with “Suffix” appended to it. This is useful for modifying an input file name with a suffix for use as an output file name.
For example, if “Base” is InputFile and “Suffix” is _Output, the process will output the string InputFile_Output. The process converts numbers to strings, so if “Base” is 2 and “Suffix” is 3, it will output 23, not 5.
