Dear Student,

In Dosbox, first of all you need to mount the drive. For example, if your BORLANDC folder is available in D drive then follow the given steps:

1)         mount D D:\

2)         D:

3)         D:\> cd borlandc\bin

4)         Now, Run the following command.

5)         D:\borlandc\bin>bc.exe

you generate the COM file by executing the following command in DOSBox?

for example bcc –EAB.COM –ID:\BORLANDC\INCLUDE –LD:\BORLANDC\LIB AB.C

(Also, make sure that your BORLNDC folder is available in drive D before executing this command.)

Regards,
