The MINSTALL program (MINSTALL.EXE) requires specific file information to install each subsystem. This file information is provided by the master control file CONTROL.SCR. The master control file, CONTROL.SCR, tells the installation program what to install, where to install it, how to display it to the user, and what system files need to be updated. CONTROL.SCR uses keywords to specify these instructions to MINSTALL.
This control file must be named CONTROL.SCR and must reside on the first media unit (diskette or CD) of the installation package. During installation, if any errors are detected in the master control file, the errors are logged in the MINSTALL.LOG file. (See Installation LOG File.)
The CONTROL.SCR file consists of a header section and a subsystem definition section. The header section comes first and provides general information for the installation procedure. The subsystem definition section comes next and provides information about the subsystems in the installation package.
