case. For example, %.3s will return the first three characters of the
local host name, and %-.3s will return the last three characters.
To automatically assign a new device name for each successive con-
nection, either enter %dN% after the name, where N is a decimal
value, or %xN%, where N is a hexadecimal value. Each time the
host requests the device name a counter will be incremented modu-
lus N and substituted into the device name.
For example, TEST%d4% will give TEST1 on first connect,
TEST2 on second, TEST3 on third, TEST0 on fourth, TEST1 on
fifth and so on.
TEST%d100% will give TEST1 on first connect, TEST2 on sec-
ond, ... TEST99 on 99th, TEST0 on 100th, TEST1 on 101st and so
on.
These values are preserved over power off, so the first connection of
any given power on may not be TEST1. Assume that the start point
is random. In addition there is a single counter for the unit so concur-
rent sessions will start from subsequent values. For example, if ses-
sion one uses TEST1 then session two will use TEST2.
Where a device name collision occurs (i.e. the device name is
already in use on the host) the host will ask again for the device
name during the same connection. In this case TEST1, TEST2, ...
may all be tried in one connection until the host accepts one, or all
possibilities have been tried. In the latter case the same name is sent
twice in succession to indicate to the host all names have been tried.
If concurrent 5250 sessions are started before a previous session has
negotiated an acceptable device name, it is possible that the two ses-
sions will access the counter simultaneously and not all possible
names will be tried by each session. This should not cause a problem
unless the separate sessions use different modulo values (for exam-
ple, session one device name TEST%d4% and session two device
name ANOTHER%d100%) or are connecting to different hosts.
Note: There are separate counters for the IBM 3270 and IBM 5250
emulations.
