Translate tables are used to translate data between the EBCDIC character set and the ASCII character set. EBCDIC is used
on IBM mainframe and iSeries systems for character formatting whereas ASCII is used in the PC environment for character formation.
When a character arrives from the host it is translated from EBCDIC to ASCII. When a character is sent to the host it is translated
from ASCII to EBCDIC.
Important
Translate table modifications must only be made when problems occur running a host application.
To access the translate tables:
|
1. |
From the BlueZone menu bar, click . The Session Configuration property sheet opens.
|
|
2. |
Click the 3270 Emulation tab. The 3270 Emulation property sheet displays Translation, LU1 Print Options, LU3 Print Options and LU1 / LU3 Print Options.
|
|
3. |
In the Translation section, click Translate Tables. The Translate Tables menu displays two tabs: EBCDIC to ASCII and ASCII to EBCDIC.
|
|
4. |
Select the desired translation table. |
How the tables work
To demonstrate how the tables work we will use the character 'A'. Please note that all ASCII and EBCDIC values shown below
are hexadecimal values.
In the ASCII Code table the character 'A' is represented by the value '41' (in hex). In the EBCDIC Code table the character
'A' is represented by the value 'C1'.
|
1. |
Starting on the ASCII to EBCDIC page, look at Column 4x Row x1 and you will see the character 'A'. Click the Edit button to
switch to the values mode and will see the EBCDIC value 'C1'. This is the value that will be sent to the host when the 'A'
key is pressed on the keyboard.
|
|
2. |
Now to verify that this is the correct value, let's follow the same sequence in reverse. Look at the EBCDIC to BUFFER page
and examine the Column Cx Row x1, you should see the character 'A'. Click the Edit button, to switch to the values mode and
you will see the ASCII value '41'. This is the value that will be sent from the host when an 'A' is requested.

This explanation shows the standard sequence of events when translating characters. This sequence looks the same in both directions,
only reversed. For example:
ASCII to EBCDIC
41 -> C1
EBCDIC to ASCII
C1 -> 41
