Macro Description
Attribute Macros
Controlling MKS Make
OSRELEASE Defined internally, expands to a string giving the release
number of your current operating system.
The attribute macros let you turn global attributes on and off. You use
the macros by assigning them a value. If you assign a NULL value to
the macro, make turns off the associated attribute. If you assign a non-
NULL value to the macro, MKS Make turns on the associated
attribute and gives all targets that attribute.
The following macros correspond to attributes of the same name:
.EPILOG
.PRECIOUS
.PROLOG
.SILENT
PWD Defined internally, expands to the full path name of the
present working directory (that is, the directory that
MKS Make considers the current directory).
SHELL Set by the default rules and may be changed by you,
expands to the full path to the executable image used as
the shell (command interpreter) when processing singleline
recipes. You must define this macro if you use recipes
that require execution by a shell.
The default rules assign a value to this macro by
inspecting the value of the SHELL environment variable. If
this variable has no value, MKS Make gives it the value of
the COMSPEC environment variable.
SWITCHAR Defined internally, expands to the switch character
currently used to mark command-line options.
