- For EPICS builds on HP700 and Alpha OSF/1, set an environment variable "EPICS"
- to the base of the EPICS directory to do builds in (the directory where

-
- If you are currently in the base directory, then do the following:

 Notes:
 
-1. In order to build and use EPICS under Solaris 2, you must include
-various directories in your path in the order given below, in addition
-to those named in base/README. Some of these directories may already be
-included in your path from your .login script or .cshrc file, so be
-careful that the ordering is correct.
+1. In order to build EPICS under Solaris 2, you must ensure that the
+solaris directory /usr/ccs/bin is in your search path.
 
-	setenv PATH /usr/ucb:/usr/bin:/usr/ccs/bin:$PATH
+2. It is not possible to compile EPICS under Solaris 2 using only the
+GNU gcc compiler -- you must have the Sun SPARCworks ANSI C compiler.
 
-2. It is not possible to compile the whole of EPICS under Solaris 2
-using only the GNU gcc compiler - some routines which are needed (for
-example quiet_nan()) have been unbundled by Sun and are provided with
-their ANSI C compiler.  The path to the Sun compiler is explicitly set
-using the SPARCWORKS definition in the file CONFIG_SITE.Unix.solaris
-
-3. EPICS must be compiled and linked using the UCB compatability
-libraries.  The definitions UCB_LIB and UCB_INCLUDE are used here to
-refer to these libraries and their header files, and the tools provided
-within /usr/ucb must be used in preference to the System V ones, hence
-the above path ordering.
+3. EPICS under Solaris 2 no longer uses the UCB compatability libraries.
+In order to ensure that the /usr/ucblib files are not inherited, you
+should ensure that your LD_LIBRARY_PATH environment variable does not
+include /usr/ucblib when you build any of the host tools.

+.TH SF2DB 1 "04 Nov 1993"
+.SH NAME
+sf2db \- make a new ascii database ".db" file from an old dct short form report
+.SH SYNOPSIS
+.B sf2db
+.B name
+<
+.B short_form_rpt
+>
+.B db_file
+.SH AVAILABILITY
+The tool in available under Unix from the EPICS add_on directory.
+.SH DESCRIPTION
+.LP
+This tool reads a dct short form report file from standard in and
+writes a ".db" (new ascii database format) file to standard out.  A
+.B name
+must be given for the database.  The name specified is used to name
+the ".database" file when the ".db" file is converted to a binary ".database".
+.sp
+The output of this tool can be imported to gdct(1) for editting.
+.SH "EXAMPLE USAGE"
+.LP
+sf2db test < old.short.form > new.db
+.sp
+This command will read old.short.form and produce the file new.db.  When
+new.db is fed into db2database(1), a binary database file will be created
+named test.database.
+.SH "SEE ALSO"

+ * The next page contains macros for defining requests.
+ * As an example the following defines a buffer to accept an array
+ * of 10 float values + DBR_STATUS and DBR_TIME options
+ *
+ * struct {
+ *	DBRstatus
+ *	DBRtime
+ *	float value[10]
+ * } buffer;
+ *
+ * IMPORTANT!! The DBRoptions must be given in the order that they
+ *             appear in the Data Base Request Options #defines
+ *
+ * The associated dbGetField call is:
+ *
+ * long options,number_elements;
+ * ...
+ * options = DBR_STATUS|DBR_TIME;
+ * number_elements = 10;
+ * rtnval=dbGetField(paddr,DBR_FLOAT,&buffer,&options,&number_elements);
+ *	
+ * When dbGetField returns:
+ *	rtnval is error status (0 means success)
+ *	options has a bit set for each option that was accepted
+ *	number_elements is actual number of elements obtained
+ *
+ * The individual items can be refered to by the expressions::
+ *
+ * buffer.status
+ * buffer.severity
+ * buffer.err_status
+ * buffer.epoch_seconds
+ * buffer.nano_seconds
+ * buffer.value[i]
+ *
+ * The following is also a valid declaration:
+ *
+ * typedef struct {
+ *	DBRstatus
+ *	DBRtime
+ *	float value[10]
+ * } MYBUFFER;
+ *
+ * With this definition you can give definitions such as the following:
+ *
+ * MYBUFFER *pbuf1;
+ * MYBUFFER buf;
