LINK
/NOBITMAP causes the I and D space bitmaps to be suppressed. The absence
of /NOBITMAP causes both I and D space bitmaps to be generated. One cannot
be generated and the other suppressed.
/BOTTOM:value[:type]
Specifies the lowest address to be used by the relocatable code in the load module.
The value argument specifies a six-digit unsigned, even octal number. If you do
not use this option, the linker positions the load module so that the lowest address
is location 1000
8
. This option is invalid for foreground links.
The optional type argument to the value can be DAS or INS and is used only if
you also specify the /IDSPACE option. When specified with /IDSPACE:
• /BOTTOM:value:DAS specifies the lowest address to be used by the D-space
code in the load module.
• /BOTTOM:value:INS specifies the lowest address to be used by the D-space
code in the load module.
• /BOTTOM:value:INS is the default; that is, /BOTTOM:value:INS and
/BOTTOM:value have the same effect.
If /BOTTOM is not used to specify a value for either the I-space or D-space code,
1000
8
is used as the default for that space or spaces.
/BOTTOM and /TOP are mutually exclusive options for a particular space.
However, you can use /BOTTOM for one data space and /TOP for the other. For
example, /BOTTOM:value:DAS and /TOP:value:INS are valid to use together.
/BOUNDARY[:value[:type]]
Starts a specific program section in the root on a particular address boundary.
LINK generates a whole-number multiple of the value you specify for the starting
address of the program section. If specified, the value argument must be a power
of 2. LINK extends the size of the previous program section to accommodate the
new starting address for the specific section.
The optional type argument to the value can be DAS or INS and is used only if
you also specify the /IDSPACE option. When specified with /IDSPACE:
• /BOUNDARY:value:DAS specifies a particular address boundary at which a
specified D-space PSECT in the root begins.
• /BOUNDARY:value:INS specifies a particular address boundary at which a
specified I-space PSECT in the root begins.
• /BOUNDARY:value:INS is the default; that is, /BOUNDARY:value:INS has
the same effect as /BOUNDARY:value.
/BOUNDARY and /TOP are mutually exclusive options for a particular space.
However, you can use /BOUNDARY for one data space and /TOP for the other.
For example, /BOUNDARY:value:DAS and /TOP:value:INS are valid to use
together.
