Issue/Introduction

When using REPCR=YES, how does XCOM Data Transport determine what LRECL to use when creating the file?

Environment

• XCOM™ Data Transport® for z/OS
• XCOM™ Data Transport® for Windows
• XCOM™ Data Transport® for Linux PC

Resolution

If receiving from another z/OS partner, XCOM will use the DCB information of the originating file if it isn't specified in the SYSIN01 parameters. Whenever allocation information cannot be derived from anywhere else, it is taken from the default values table (XCOMDFLT), but there are no XCOMDFLT parameters for the DCB information (ie RECFM, LRECL and BLKSIZE).
It is the initiating partner that sets default values for LRECL.
XCOM for Data Transport for Windows, UNIX and Linux applies these defaults:
DCB=(RECFM=VB,LRECL=160,BLKSIZE=800),SPACE=(CYL,(1,1))
