How USERIDMGREX.EXE works is not clear from the question. If it is a program that displays it's own prompt and waits for the user to type an input then it may be possible to redirect standard input from a file. This is most easily demonstrated with the command processor itself and a text file containing one command per line.
echo Display system time and date
At a command prompt we can issue the command
e:>cmd < commands.txt
and see the output
e:> cmd < commands.txt
