Hi all,

   I've been using INFOZIP without any problems for
awhile.  I've recently have a need to compress a file
that has 2.8+ million rows with a lrecl of 445.  Last
night I let the compress run for 4.5 hours before=20
canceling it.  My question is can INFOZIP handle files
this big?  This is the JCL I'm using:

//STEP01   EXEC PGM=3DZIP,PARM=3D'''TEST.LOAD.INPUT'' DD:OUT -av'
//STEPLIB  DD   DSN=3DINFOZIP.LOAD,DISP=3DSHR                   =20
//SYSOUT   DD   SYSOUT=3D*                                            =20
//SYSPRINT DD   SYSOUT=3D*                                            =20
//OUT      DD   DSN=3DTEST.LOAD.ZIP,                     =20
//            DISP=3D(NEW,CATLG,DELETE),                              =20
//            DCB=3D(RECFM=3DFB,LRECL=3D80,BLKSIZE=3D0),                 =
   =20
//            UNIT=3DDISK,SPACE=3D(CYL,(1500,50),RLSE) =20

Any help or suggestions would be very much appreciated. =20
