Answer 1

Are you saying you want to use an OS level environment variable in a MaxL statement to substitute for an entire file name? I am going to illustrate Windows, but do it your own way in *nix if you want.
YourCallingCode.cmd
REM Note the \\ and then the \\, you had \\ and \
SET curmon=c:\\ABC\\datafile_21_AUG.txt 
REM Call MaxL with a paramenter
startMaxL.cmd DoItForTheCurrentMonth.msh %curmon%DoItForTheCurrentMonth.msh
login blah blah for blah ;
import database appname.dbname data from local text data_file $curmon using server rules_file "rulefile"
     on error abort ;The trick is to change whatever's in % and % and replace it with a $ in the MaxL script.
I gave a presentation last year on MaxL at ODTUG Kaleidoscope. If you go to http://www.odtug.com, then Tech Resources, then Essbase, then search on my name, you'll find "Master Essbase with MaxL Automation". More than you could ever want to know about MaxL, variables (parameter, environment, and explicitly declared), scripting, etc., etc., are all there for the taking. If you're not already a member, you'll have to join, but an associate membership is free. You can then download my presentation and all of the others. It is a treasure chest of technical tips and knowledge.
Yes, I am a fan a member of the Hyperion SIG, so I am ever so slightly biased. Regardless, it is good information, for free.

If you want to substitute part of the data file name, you can do that too:
set curmon=21_AUG
Your MaxL statement would look like:
import database appname.dbname data from local text data_file "c:\\ABC\\datafile_$curmon.txt" using server rules_file "rulefile"
     on error abort ;
