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...

Filenames

It is important to understand DOS file naming conventions and their use. Here, filenames and some special filename "tools" called wild cards and literals are described. What is a File name?   Every program and data file is given a name to differentiate it from other programs and data files. A program is one or more computer instructions collected into a file. A data file is normally a collection of characters (or data) that make up a document, like a letter, or a database, like a collection of accounting transactions or customer records. Descriptive filenames are normally used. For example, if you create and save a letter to Mom, you might give it the filename MOM.LTR. A letter to Dad could be called DAD.LTR. A word processing program file might have the filename WP.COM. Examine these filenames a little closer. First, notice that each filename is meaningful. This is important if you want to know what is in a file by looking at its name. Obscure filenames are of little u...
