Status: Unverified
GOAL:
Possible workaround for customers experiencing problems when trying to display the European currency symbol (?) on a Progress client when the symbol is stored in a DB2/400 database.
FACT(s) (Environment):
OS/400 V4R3
Progress/400 DataServer
Progress 8.x
Progress/400 DataServer version 8.0C60
CAUSE:
The difficulty stems from incorrect mapping between the differing code
pages used on the AS/400 and the Progress client. For example, a Progress client using a codepage of ISO8859-1 will display a Euro currency symbol from an AS/400 using IBM037 as (¤).
FIX:
You can correct the problem by editing and recompiling the convmap conversion tables. Follow these steps:
1) Connect to the DataServer from the client in order to obtain the code page information of both the AS/400 DataServer and the Progress client session stream.
a) From the Progress User Interface Builder or AppBuilder, read the session information from Data Administration/Utilities/Information (DataBase code page and session stream).
b) Check the dlc/prolang/convmap/weuroebc.dat (for Progress Version 8) or dlc/prolang/convmap/weurocnv.dat (for Progress Version 9) and ensure there is a conversion table for conversions between the AS/400 code page and the Progress client code page.
If there is no available conversion table, you can create one for the purpose. See the section "Using Character Sets and Code Pages" in the "Progress Internationalization Guide."
2) Execute the following code as a Native 4GL Client on the AS/400:
DEFINE VARIABLE i AS INTEGER.
OUTPUT TO "codepage.txt".
DO i = 30 TO 255:
DISPLAY i AT 1 FORMAT "99999"
CHR(i) AT 20 FORMAT "XXXX" WITH FRAME a DOWN.
DOWN WITH FRAME a.
END.
OUTPUT CLOSE.
From the AS/400 command line execute the procedure as:
STRPROCLI STRPROC(procedure.p)
3) The codepage.txt file should display the European currency symbol that is seen on the AS/400 and its corresponding value within the code page.
4) Edit the dlc/prolang/convmap/weuroebc.dat (for Version 8) or dlc/prolang/convmap/weurocnv.dat (for Progress Version 9), changing the conversion table identified in Step 1. The position used to display the European currency symbol on the client must correspond to the value used by the AS/400 code page.
It is important to understand that positions need to change according to the direction that the conversion tables convert data. Two examples of conversion directions are from ISO8859-1 to IBM037 (client to AS/400) and from IBM297 to ISO8859-1 (AS/400 to client).
NOTE: As conversion tables are being changed, it is possible that data could be lost. For this reason it is recommended that you have a valid database backup, and you use "proutil convchar charscan" on a Progress version of the database.
This will ensure that the values being changed are not stored in the database and therefore will not risk corruption.
a) In dlc/prolang/convmap/weuroebc.dat (Progress version 8) there is a table which converts Iso8859-1 to IBM037 (client to AS/400)i.e.:
# This contains the data needed to convert from # iso8859-1 to ibm037

If the value obtained at Step 3 is 159, then position 128 (the ISO8859-1 value for the European currency symbol) in the table should have a value of 159.
The value currently stored at this position (033) should be moved to the position where 159 currently resides, i.e. table position 164.
b) There is a table in dlc/prolang/convmap/weuroebc.dat that converts IBM297 to Iso8859-1 (AS/400 to client), i.e.:
# Convert from IBM297 (EBCDIC France)
# to ISO8859-1 (default Progress internal)

If the value obtained at step 3 is 159, then position 159 should correspond to the Iso8859-1 value for the European currency symbol 128. You should change this value to 128 and move the value currently stored there (164) to the position where 128 currently resides (033).
5) Recompile the convmap.dat file using the proutil utility (See Solution 16242).
6) Start the Progress client session using the Conversion Map Startup parameter (-convmap) if necessary and display the European currency symbol on the client.
This should now be correct.
