DSEVOC Output control
Name DSEVOC
Output control
Purpose This subprogram can be called at any point after subprogram DSEVIN to alter
the output message level and the Fortran output unit number for message
output.
Usage VECLIB:
INTEGER*4 msglvl, output
REAL*8 global(150)
CALL DSEVOC(msglvl, output, global)
VECLIB8:
INTEGER*8 msglvl, output
REAL*8 global(150)
CALL DSEVOC(msglvl, output, global)
Input msglvl Message level for printable output:
msglvl ≤ 0 Suppress all output.
msglvl = 1 Error messages, summary statistics
and inertia information.
msglvl = 2 More complete statistics.
msglvl = 3 First stage of debugging output.
msglvl = 4 Complete debugging output.
output Fortran logical unit number to which all output will be
written.
Updated global Global communications array for this problem. This
array must be passed, untouched by the user, to
successive subroutines in this package.
Example Increase message level from 1 to 2 while leaving the Fortran logical unit
number for the output unit at 6.
REAL*8 GLOBAL(150)
CALL DSEVOC (2,6,GLOBAL)
