A question for everyone.

Doesn't seem like there is one. When config.sys is running, command.com hasn't been loaded yet, which means internal commands can't be used;
you can only use commands in io.sys or external commands;
there doesn't seem to be one in io.sys, and no external command for this has been developed yet;
if you really want to pause, you can only make a menu (like the Win98 boot disk).
I really don't know why you want to pause, the point is not very big! After all, config.sys is for setting the system environment, and everyone wants to do it in one go~

Re martin325:

To pause before executing all memory configuration statements, you need to use a boot menu; the menudefault item can be used to set the pause time.

To pause before executing memory configuration statements such as device/devicehigh, you can add a question mark after the command. For details, please refer to the following material quoted from the PDOS6.22 help document.

Special characters in the CONFIG.SYS file

The CONFIG.SYS file can also include the following special characters:

; Indicates that this line is a comment line and will not be executed. This
character should be placed at the beginning of the line.
(You can also use the REM command to insert comments).

? Specifies that before executing the current command, MS-DOS asks the user
for confirmation first. The ? should be added before the equal sign. For example, if
the command DOS=HIGH is changed to DOS?=HIGH, then before executing that command,
confirmation is required.
If confirmation is needed before executing the command DEVICEHIGH /L:1,7280=MYFILE.SYS,
this command can be changed to DEVICEHIGH? /L:1,7280=MYFILE.SYS.

Skipping CONFIG.SYS and AUTOEXEC.BAT commands

If the system has problems and you suspect they may be caused by commands in the CONFIG.SYS file,
you may want to skip some or all commands in CONFIG.SYS.

To skip all commands in CONFIG.SYS and AUTOEXEC.BAT, when the system starts and the screen shows
"Starting MS-DOS...（Starting MS-DOS）", immediately press the F5 key.

To skip individual commands in CONFIG.SYS and AUTOEXEC.BAT, press the F8 key. MS-DOS asks
the user for confirmation before executing each command. To execute all remaining startup commands, press the Esc key; to skip all remaining commands, press the F5 key.

To disable this function, add the command <SWITCHES /N> to CONFIG.SYS.

Learned something, so io.sys actually has such a function!
