LOC86 changes a relocatable 8086 object module into an absolute object module.
As figure 5-1 illustrates, LOC86 takes a single 8086 object module as input and out-
puts a located object file and, optionally, a print file. The print file output contains
diagnostic information. The object file contains absolute object code.
This chapter provides details concerning the LOC86 invocation, controls, and print
file. For definition of file-naming and syntax notation conventions used in this
chapter, refer to Notational Conventions following the Preface. For a summary of
the LOC86 controls and information on error and warning messages that may be
produced, refer to Appendix G. For details concerning LOC86 segment support
capabilities, refer to Appendix C.

Figure 5-1. LOC86 Input and Output Files
LOC86 Invocation Line
The general syntax for the invocation line is:
[directory-name]
L 0 C 86
inputfile
[T 0
objectfile ][controls]
121616-6
The
input file
is a file containing an object module to be located. It is usually, but
not necessarily, the output from LINK86.
TO
object file
specifies the file to receive the located object module. In most cases
this is an executable file. If
object file
is not specified, then output will be directed to
a file that has the same pathname as the
input file,
except it will have no extension.
The
controls
may be any subset of the controls described in the next section.
LOC86 Controls
The
controls
are described in table 5-1.
If you specify the same control more than once in the same invocation line, only the
last version entered counts. For example, if you enter NOMAP, and then later
decide you want a locate map, you can enter the MAP control without error. The
second version of the control is recognized and the first is ignored.
At the end of this document you will find operating system-specific examples of the
LOC86 controls. Fold out the pages containing the examples relevant to your
operating environment and use them in conjunction with the syntax conventions
provided in this chapter.
