SUBROUTINE SVOUT (N, SX, IFMT, IDIGIT)

C***DESCRIPTION
C
C SINGLE PRECISION VECTOR OUTPUT ROUTINE.
C
C INPUT..
C
C N,SX(*) PRINT THE SINGLE PRECISION ARRAY SX(I),I=1,...,N, ON
C OUTPUT UNIT LOUT. THE HEADING IN THE FORTRAN FORMAT
C STATEMENT IFMT(*), DESCRIBED BELOW, IS PRINTED AS A FIRST
C STEP. THE COMPONENTS SX(I) ARE INDEXED, ON OUTPUT,
C IN A PLEASANT FORMAT.
C IFMT(*) A FORTRAN FORMAT STATEMENT. THIS IS PRINTED ON OUTPUT
C UNIT LOUT WITH THE VARIABLE FORMAT FORTRAN STATEMENT
C WRITE(LOUT,IFMT)
C IDIGIT PRINT AT LEAST ABS(IDIGIT) DECIMAL DIGITS PER NUMBER.
C THE SUBPROGRAM WILL CHOOSE THAT INTEGER 4,6,10 OR 14
C WHICH WILL PRINT AT LEAST ABS(IDIGIT) NUMBER OF
C PLACES. IF IDIGIT.LT.0, 72 PRINTING COLUMNS ARE UTILIZED
C TO WRITE EACH LINE OF OUTPUT OF THE ARRAY SX(*). (THIS
C CAN BE USED ON MOST TIME-SHARING TERMINALS). IF
C IDIGIT.GE.0, 133 PRINTING COLUMNS ARE UTILIZED. (THIS CAN
C BE USED ON MOST LINE PRINTERS).
C
C EXAMPLE..
C
C PRINT AN ARRAY CALLED (COSTS OF PURCHASES) OF LENGTH 100 SHOWING
C 6 DECIMAL DIGITS PER NUMBER. THE USER IS RUNNING ON A TIME-SHARING
C SYSTEM WITH A 72 COLUMN OUTPUT DEVICE.
C
C DIMENSION COSTS(100)
C N = 100
C IDIGIT = -6
C CALL SVOUT(N,COSTS,'(''1COSTS OF PURCHASES'')',IDIGIT)

C***SEE ALSO SPLP
C***ROUTINES CALLED I1MACH
C***REVISION HISTORY (YYMMDD)
C 811215 DATE WRITTEN
C 890531 Changed all specific intrinsics to generic. (WRB)
C 891107 Added comma after 1P edit descriptor in FORMAT
C statements. (WRB)
C 891214 Prologue converted to Version 4.0 format. (BAB)
C 900328 Added TYPE section. (WRB)
