4.3.8.3 PSECT
The PSECT directive declares or resumes a program section. It takes as arguments a name and,
optionally, a comma-separated list of flags. The allowed flags are listed in Table 4.6, below.
flags need not be repeated.
Once a psect has been declared it may be resumed later by another PSECT directive, however the
abs defines the current psect as being absolute, i.e. it is to start at location 0. This does
not mean that this module’s contribution to the psect will start at 0, since other modules may
contribute to the same psect.
The bit flag specifies that a psect hold objects that are 1 bit long. Such psects have a scale
value of 8 to indicate that there are 8 addressable units to each byte of storage.
The class flag specifies a class name for this psect. Class names are used to allow local psects
to be referred to by a class name at link time, since they cannot be referred to by their own
name. Class names are also useful where psects need only be positioned anywhere within a
range of addresses rather than at one specific address.
The delta flag defines the size of an addressing unit. In other words, the number of bytes
covered for an increment in the address.
