SUBROUTINE AGSETC (TPID,CUSR)
C
CHARACTER*(*) TPID,CUSR
C
DIMENSION FURA(1)
C
C The routine AGSETC is used to set the values of individual AUTOGRAPH
C parameters which intrinsically represent character strings. TPID is a
C parameter identifier. CUSR is a character string. The situation is
C complicated by the fact that the character string may be either a dash
C pattern, the name of a label, the line-end character, or the text of a
C line, all of which are treated differently.
C
C Define a local variable to hold the "line-end" character.
C
CHARACTER*1 LEND
C
C See what kind of parameter is being set.
C
CALL AGCTCS (TPID,ITCS)
C
C If the parameter is not intrinsically of type character, log an error.
C
IF (ITCS.EQ.0) GO TO 901
C
C Find the length of the string, which may or may not actually be used.
C (On the Cray, at least, it may be zero if the wrong type of argument
C was used.)
C
ILEN=LEN(CUSR)
C
C Retrieve the current (integer) value of the parameter.
C
CALL AGGETI (TPID,ITMP)
C
C Check for a dash pattern.
C
IF (ITCS.EQ.1) THEN
CALL AGGETI ('DASH/LENG.',NCHR)
IF (ILEN.GT.0.AND.ILEN.LT.NCHR) NCHR=ILEN
CALL AGRPCH (CUSR,NCHR,ITMP)
C
C Check for a label name.
C
ELSE IF (ITCS.EQ.2) THEN
CALL AGRPCH (CUSR,MAX0(1,ILEN),ITMP)
C
C Check for the line-end character.
C
ELSE IF (ITCS.EQ.3) THEN
CALL AGRPCH (CUSR,1,ITMP)
C
C Check for the text of a label.
C
ELSE IF (ITCS.EQ.4) THEN
CALL AGGETI ('LINE/MAXI.',NCHR)
IF (ILEN.GT.0) NCHR=MIN0(NCHR,ILEN)
CALL AGGETC ('LINE/END .',LEND)
DO 101 I=1,NCHR
IF (CUSR(I:I).EQ.LEND) THEN
NCHR=I-1
GO TO 102
END IF
101 CONTINUE
C
102 CALL AGRPCH (CUSR,NCHR,ITMP)
C
END IF
C
C Transfer the generated value to the list of AUTOGRAPH parameters.
C
FURA(1)=FLOAT(ITMP)
CALL AGSETP (TPID,FURA,1)
C
C Done.
