The Assembler provides a series of standard space and subspace
definitions that you can use to simplify the writing of an assembly
program. These definitions are duplicated in the system file /usr/lib/pcc_prefix.s.
Because this file is relatively large and may change with new releases
of the Assembler, you can view the most recent version of the file
on your terminal screen by typing the command: more /usr/lib/pcc_prefix.s |
Table 4-3 “Predefined Subspace Directives ” lists
the predefined directives for establishing standard spaces and subspaces. Table 4-3 Predefined Subspace Directives Directive | Space Name | Default Parameters
