CHANGING OBJECT PROGRAMS
Files which contain relocatable object code and have a
filetype of TEXT can be read into core storage and have
linkages resolved by the LOAD, USEI' and REUSE commands.
Five types of cards can be added to a TEXT file. These are
the Set Location counter (SLC), the Include Control Section
(ICS), the Replace (REP)" the ENTRY, and the LIBRARY cards.
These are used to set the core location where LOAD begins
placing the file in core, to make corrections and additions
to the relocatable object code in core once the file is
loaded, to specify entry points, and to specify references
that are not to be resolved. These cards can be added to
the TEXT file(s) which have been OFFLINE PUNCH'ed and can
then be read back in, or they can be added using the SPLIT
and COMBINE commands or the EDIT command.
