C-Series Applications
Applications written for pre-D-series software can run on D-series software but must
be assigned to a low PIN.
File Names, Device
Names, and Process
Names
D-series Exchange/SNA supports the naming conventions and restrictions defined in
C-series software for disk files, processes, disk volumes, and devices. However,
D-series software does not provide a default subvolume name when you specify a file
name and a volume name. (See “File Name Syntax” below.)
D-series Exchange/SNA does not support process file names with a sequence number.
File Name Syntax The D-series operating system does not provide a default subvolume name when a
volume name is given in the file name syntax. You must specify the subvolume name.
The correct syntax for a file name is as follows:
[[\ node-name. ] [[$ volume-name. ] subvolume-name. ]] fileid
Error Message An error message (SNCI14E I/O ERROR ON <line server name>, ERROR 560) is
displayed in the following situations:
1. When RJECIS is running at a high PIN and a CONNECT command is issued to an
existing line server running on a remote C-series system.
2. When RJECIS is running on a C-series system and an attempt is made to start or
connect with a line server running on a D-series system at a high PIN.
