MEM

MEM

The MEM command was introduced in DOS version 4.01 and memory information. The MEM command is entered alone or with a modified slightly in MS-DOS 5.00. MEM is used to display system
memory information.
The MEM command is entered alone or with a parameter.
MEM-Displays to all system memory values, including expanded and extended memory values.

MEM PROGRAM--Displays programs presently loaded in memory with used and unused memory. You may use /P if you are using DOS 5.00

MEM/DEBUG--Dispiays a list of programs, device drivers, install drivers, and used unused memory. You may use / if you are using DOS 5.00.

MEM CLASSIFY (or MEM /C)-Displays programs and cor-responding memory usage. The largest available memory block is also displayed. You may use /C if you are using DOS 5.00.

Typing MEM and pressing Enter displays information similar to the
following (typical of DOS 5.00):

C:\>MEM
      
           655350 bytes total conventional memory
           655360 bytes available to MS-DOS
           604016 largest executable. program size

    35389:4 bytes total contiguous extended decay
            0 bytes availbale contiguous extended memory
    2424832 bytes available XMS memory
                   MS-DOS resident in High Memory Area

Path

The PATH command is used to provide access to files located in other directories or on other disks. The PATH command is usually entered as a line in an AUTOEXEC.BAT (or batch) file, which most often contains one or more DOS commands. The AUTOEXEC.BAT file is automatically executed upon system turn-on to run one or more desired programs without the need for user intervention. Other batch  files are executed upon command. When an AUTOEXEC.CAT file is used, each command contained in the file executes as it is encountered. The creation and use of batch files is described in Section 8. To illustrate the PATH command, assume you have a program named GATOR.COM that is located in a sub directory. You are not sure if it is cn disk C or disk A, so you want to search both disks and execute the command when found. To complicate matters, you are not sure if the program is in the SWAMP sub directory or the MUD sub directory. Here is where the PATH command comes to your rescue. To set up a search...

DOS Programs (2)

Internal and External Commands Internal and External Commands:  There are  two kinds of DOS commands. These are called internal and external. The internal commands are loaded into memory when DOS is booted. Internal commands are always available for your use, although they are not seen when you display the disk directory of filenames on your screen. Some internal commands are: COPY                               copies files DEL or ERASE               delete files DIR                                  list are directory of filenames on the logged disk PROMPT                         changes the form of the system prompt REN                      ...

Section 4 Introduction

Introduction Section 3 introduced you to the Dir command. You used it to display a list of filenames. This section provides more information about filenames and disk directories, sometimes called file paths. Filenames are given to text, data, and program files that reside on a disk. Directory (or path) names are also given to disk directories, which are convenient subdivisions in which categories or families of files may te collected and maintained. Several commands are available to create, list, or delete filenames and directory names. These include: MKDIR (or MD)            Make (or create a new sub directory. CHDIR (or CD)            Change to (or log) a named directory. RMDIR (or RD)            Remove a named directory. PATH                            Provide automatic access to program and batch files located within one or m...
