Passing arguments to BAT file does not work exactly the same in DOSbox as is does in other environments (like Win98). Consider the following file (TEST.BAT)

On Win98, '''TEST.BAT 99''' produces:
 
<code><pre>-99- 0990 1991 2992</pre></code>
 
Whereas DOSbox 0.70 produces:
 
<code><pre>-99- 0990 1 2</pre></code>
 
A work-around is to change TEST.BAT to:
 
<code><pre>SET X=%1
 
echo -%X%- 0%X%0 1%X%1 2%X%2</pre></code>
 
This coding style has the added benefit of allowing order of arguments to be changed at some future time without major impact on your script.

The command line inside DOSBox is very similar to the one of a real DOS system, such as displaying the command-line prompt "C:\>" and waiting for user input. Nevertheless, the default initial drive of DOSBox is [[ZDrive|Z:]], a Virtual Internal Drive, instead of A: or C: when booting from a real DOS system. In either case the user can type a DOS command such as "DIR" which will be executed after the ENTER key is typed. After that the command-line prompt will be shown again to wait for another user input. Please see [[commands]] for a list of supported commands in DOSBox.
Please note that you will rarely encounter this problem (dosbox parses %11 as then eleventh parameter)
 
This has been repaired in the cvs of dosbox.
 
Please submit a bug report next time.

The command line inside DOSBox is very similar to the one of a real DOS system, such as displaying the command-line prompt "C:\>" and waiting for user input. Nevertheless, the default initial drive of DOSBox is Z:, a Virtual Internal Drive, instead of A: or C: when booting from a real DOS system. In either case the user can type a DOS command such as "DIR" which will be executed after the ENTER key is typed. After that the command-line prompt will be shown again to wait for another user input. Please see commands for a list of supported commands in DOSBox.
