Conversion of
C-Series Applications
In pre-C30 software, the line server returns a reply code of 0 (FEOK) to the startup
message when you start the line server (RJESV) with a call to NEWPROCESS. D-series
Exchange/RJE returns a reply code of 70. To convert a pre-C-30 application modify its
code so that it recognizes the reply code of 70.
An unconverted application must be assigned to a low PIN to run in a D-series
operating system. An unconverted application cannot take advantage of the high
PINs on the D-series operating system.
File Names, Device
Names, and Process
Names
D-series Exchange/RJE 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/RJE 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 RJECIR 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 RJECIR 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.
