SUBTTL DEFINITIONS -- Error Handling -- $ERROR
;Error messages in SORT are handled via the $ERROR macro below. Four standard
;types of messages are handled, as shown below.
;
; TYPE CALL RESULTING MESSAGE
;
; Informative $ERROR ([,xxx,<Text>) [SRTxxx Text]
; Warning $ERROR (%,xxx,<Text>) %SRTxxx Text
; Fatal $ERROR (?,xxx,<Text>) ?SRTxxx Text
; Operator intervention $ERROR ($,xxx,<Text>) $SRTxxx Text
;
;For fatal error messages, $ERROR automatically generates a call to the $DIE
;macro to abort the sort, possibly returning error information for the FORTRAN
;user.
;
;Error messages which contain text that is a function of run-time parameters are
;handled by specifying '+' as the fourth argument to $ERROR, then using the
;$MORE or $CHAR macros as needed, and finishing with $CRLF. In this case, the
;final message disposition must be performed by manually calling $DIE for fatal
;errors.
;
;When some alternate cleanup should be done on fatal errors, a fifth argument
;may be specified. This is the address to transfer control to after printing the
;message. Note that this is only applicable if '+' was not specified as the
;fourth argument. If it was, then an explicit JRST may be used in place of the
;final $DIE macro.
;
;The label of $ERROR macros is E$$xxx by convention; in fact, the macro now
;generates this label automatically. If an error message routine must do some
;preliminary computations before calling $ERROR, then the actual error routine
;label should be ERRxxx.

SUBTTL DEFINITIONS -- Error Handling -- $MORE
;$MORE is used following a call to $ERROR with '+' as the fourth argument.
;Thus, a sample call might be:
;
; E$$SNR: $ERROR ([,SNR,<Sorted >,+)
; $MORE (DECIMAL,OUTREC)

SUBTTL DEFINITIONS -- Structure Macros -- Descriptions
;Program structuring macros are used throughout SORT to help enforce clean
;coding practices. There are several classes of macros available for different
;purposes. These are all described below.
;
;Note that all macros except the local label ones and PROCEDURE take an
;arbitrary comment as an argument.
;
;BEGIN, END And Local Labels.
;
;The BEGIN and END macros define the scope of a source code block. Within the
;block, special local labels are available if necessary, but the additional
;structuring macros below should be preferentially used where possilbe. Local
;label references are of the form $n, where n is 0 to 7 (don't be fooled by the
;RADIX 10 before the call to $TEMPORARY). Local label definitions are of the
;form $n%, and should be indented 2 spaces from the local left margin. Also,
;within a BEGIN - END block, $B may be used as a label for the beginning of the
;block and $E for the end. Thus, a sample block might be:
;
;BEGIN ;BEGINNING OF OUTER BLOCK
; JRST $E ;JUMPS TO SECOND END
; $1% JRST $B ;JUMPS TO FIRST BEGIN
; BEGIN ;BEGINNING OF INNER BLOCK
; JRST $1 ;JUMPS TO SECOND $1%
; JRST $E ;JUMPS TO FIRST END
; $1% JRST $B ;JUMPS TO SECOND BEGIN
; END ;END OF INNER BLOCK
; JRST $1 ;JUMPS TO FIRST $1%
; JRST $B ;JUMPS TO FIRST BEGIN
;END; ;END OF OUTER BLOCK
;
;PROCEDURE And RETURN.
;
;These macros declare the entry and exits of a procedure. The first argument to
;PROCEDURE is the instruction used to call the procedure. Currently, this must
;be one of <PUSHJ P>, <JSP T4> or <JSP P4>. The second argument is the name of
;the procedure, or an IRP-style list of names. RETURN then generates the proper
;returning instruction whenever it is used in that procedure. Finally,
;procedures should be declared inside of a BEGIN - END block, with the PROCEDURE
;macro indented 2 spaces from the local left margin, and RETURN indented with
;the surrounding code. An example is:
;
;BEGIN
; PROCEDURE (PUSHJ P,DOTHIS)
; PUSHJ P,DOTHAT
; <code to do THIS>
; RETURN
;END;
;IF, THEN, ELSE And FI.
;
;These macros implement the common IF statement construct. Between the IF and
;THEN macros should be the code to determine which case is true. Control should
;fall through to the THEN if the condition is true. Control should fall into the
;ELSE (or FI if no ELSE segment) or pass to the label $T ($F if no ELSE segment)
;if the condition is false. The THEN code segment should end by transfering
;control to the FI or the label $F. Each of these macros should be indented 2
;spaces from the local left margin, and the IFs may be nested up to a depth of
;7. Some examples are:
;
; IF WE CAN DO IT IF WE CAN DO THIS IF WE WANT ONE
; <code to tell> <code to tell> MOVE T1,NUMBER
; JRST $F JRST $T CAIN T1,1
; THEN DO IT THEN DO THIS THEN GET IT
; <code to do it> <code to do THIS> SKIPA T1,['ONE ']
; FI; JRST $F ELSE GET TWO
; ELSE DO THAT MOVE T1,['TWO ']
; <code to do THAT> FI;
; FI;
;
;CASE And ESAC.
;
;These macros define the range of a selecting statement. Each code segment
;should have a local label at its beginning, and an indexed JRST is then used to
;transfer control to the correct code segment. Each segment should transfer
;control to the label $C, or, for the last segment, fall through to the ESAC.
;The CASE, ESAC and the local labels should all be indented 2 spaces from the
;local left margin. One example is:
;
; CASE DEVICE TYPE OF (.TYDSK, .TYMTA, .TYTTY)
; MOVE T1,DEVICE
; DEVTYP T1,
; JRST ERROR
; LDB T1,[POINTR T1,TY.DEV]
; CAILE T1,.TYTTY ;RANGE CHECK
; JRST $C ;OUT OF RANGE
; JRST @[IFIWS <$1,$C,$2,$3>](T1)
;
; $1% <handle DSK:>
; JRST $C
;
; $2% <handle MTA:>
; JRST $C
;
; $3% <handle TTY:>
;; JRST $C
;
;ESAC;
;WHILE, UNTIL And FOR.
;
;These are null macros used in conjunction with BEGIN and END to better indicate
;the operation of loops. If used, they should be indented two spaces from the
;local left margin. An example:
;
; WHILE MORE TO DO
; BEGIN
; JUMPE T1,$E
; <do some more>
; SOJA T1,$B
; END;
