Configuration file
Turbo Assembler lets you put your most frequently used options
into a configuration file in the current directory.
TASM will look for a file called TASM.CFG, first in the current
directory, then (under DOS 3.0 or later) in the directory of
TASM.EXE. If it is found, it is treated as an indirect file and
processed before anything else on the command line.
The contents of the configuration file have exactly the same
format as an indirect command file.
Note: Turbo Assembler does not use environment variables to
control default options.
