This section describes how to convert the parts of a TAL, COBOL85, C, Pascal, or
TACL application that are not described in Sections 3 through 7. The topics in this
section are:
Converting applications that call file-system procedures to manage disk files,
including:
Manipulating and editing disk file names
Maintaining disk files and volumes
Converting applications that use terminal I/O operations, including a command-
interpreter interface and BREAK key handling
Converting applications that call sequential I/O (SIO) procedures
Converting Distributed Systems Management (DSM) applications that use the
Event Management Service (EMS) or the Subsystem Programmatic Interface (SPI)
Improving performance using direct transfers for I/O operations
Converting memory-management procedure calls that allocate, deallocate, and get
information about extended data segments
The box in Figure 8-1 contains the processes involved in converting an application.
The topics in this section might apply to any of the processes shown in the box for a
TAL, COBOL85, C, or Pascal application.
