----------------------------

When I run MyScript.csh it's waiting for input from the keyboard, even though I tried to redirect the contents of MyInputFile.txt to use as input.

How do I use the contents of MyInputFile.txt as the input for the source of MySourceFile?

If this can't be done using a .txt file, is there another way it can be done?

Use the standard Unix shell, not csh.
Code:
#!/bin/sh
read My_Env_Var
echo "My_Env_Var in source file is set to $My_Env_Var"

Call it with:
Code:
MyScript.sh < MyInputFile.txt
