CALL GOPEN (LUN,CHOPT,LEN,IER*)
- LUN
- ( INTEGER) logical unit number, 1
LUN<100;
- CHOPT
- ( CHARACTER*(*)) any valid combination of
FZFILE options (see [,]), the most common
being:
- I
- input file;
- O
- output file;
- X
- exchange mode file;
- LEN
- ( INTEGER) maximum record length,
for more details see routine FZFILE in the ZEBRA manual;
- IER
- ( INTEGER) error flag:
- 0
- legal open request;
- 1
- attempt to open more than 5 ZEBRA sequential files;
Opens a ZEBRA FZ file for sequential I/O of GEANT
data structures. No more than 5 files can be open at any one time.
CALL GCLOSE (LUN,IER*)
- LUN
- ( INTEGER) logical unit to be closed, if 0 all ZEBRA
FZ streams will be closed;
- IER
- ( INTEGER) error flag:
- 0
- legal close request;
- 1
- no unit was found open;
This routine closes one or all ZEBRA FZ file(s). This is a
mandatory routines for all open ZEBRA files before the end of the
program. Failure to call this routine may cause files to be incompletely
written to the storage media.
