This means that all commands and file names must be typed exactly as they are given when you are working on bama.
Most commands are in lower case.
This is not the case on Windows or bama. The directory structure is different on differenct platforms, so references to external files will need to be changed. If you are on bama, try the Unix command pwd to print your working directory. Thus, references to external files will need to be in this format. SAS on UA1VM allowed you to ignore library references, which are a basic part of the way SAS handles data files.
