Add option(s) to disable EG from interjecting the code which sets certain macro variables , i.e. _CLIENT* and _SASPROG*. Allow the particular project loaded in memory to have this option disabled by accessing it(them) from the menu under File > Project Properties.
By "code which sets certain macro variables" I'm referring strictly to the LET statements that EG adds to each program node which effectively augment the SAS environment with values generated by EG.
Also wanting that when one is using File > Export > "Export all Code in Project", that the generated macro variables would also be excluded.
