Tandy 1000 MS-DOS - Chapter 6 COMMAND REFERENCE

Chapter 4 / Batch Files
To use this file to format the Drive B disk, enter the batch file
name and the drive specification to replace %1, as shown here:
pre p dis k b: [ENTER I
The next two sections tell more about creating and executing
batch files that have dummy parameters.
Creating a Batch File With Replaceable Parameters
The dummy parameters are %0 through %9. MS-DOS always
replaces
the %0 parameter with the filename of the batch file,
unless you use the SHIFT command. It replaces the other
dummy parameters, sequentially, with the parameters you spec-
ify when you execute
the batch file. (See the SHIFT command in
Part 2 if you wish to specify more than ten dummy parameters.)
These parameters may be pathnames, drive specifications,
numeric values, or almost anything else. For example, if you
type:
copy con myfile.bat [ENTERI
copy %1.mac %2.mac [ENTERI
type %2. mac [ENTER I
t Y P e %0 • bat I ENTER I
ill] [ ENTER I
MS-DOS creates the batch file myfile.bat in the current direc-
tory
and stores the next three lines in that file.
When you execute
the file, the parameters %1 and %2 are
replaced sequentially by the pathnames you supply.
Executing a Batch File With Replaceable Parameters
To execute a batch file that has replaceable parameters, enter
the batch filespec (without its extension), followed by the param-
eters to replace the dummy parameters. For example, to execute
myfile.bat, type:
myf i le a: prog1 b: prog2 [ENTER I
myfile is substituted for %0, A:prog1 for %1, and B:prog2 for %2.
