BLDRPGMSG BUILD RPG MESSAGE TAARPGJ
The Build RPG Message tool is sample code that you can copy into a
program that assists in you in building messages.
The sample code for you to copy is in member TAARPGJR in QATTRPG. It
contains instructions for where to place the standard in your
program. If you want to copy the code into your program, you must
first use CPYTAA to copy the TAARPGJR member to a normal source file
(such as QATTRPG in TAATOOL).
In your program, a typical set of code would be:
C MOVEL'U01' ZXMSID Message ID
C EXSR ZXMSG Build msg
The previous code specifies an Message ID of U01. Any 3 characters
can be used. It would be typical to use a letter followed by 2
digits so that you can scan for a unique value in your program.
You would supply the text of U01 in an array such as:
U01 Simple message of one line.
The message ID should be in the first 3 bytes followed by a blank
The message text is built up in the ZZMSDS data structure which is
part of the standard code to be copied into your program. It is then
up to your program to send the message or print it. For example, you
could use the TAA Tool SNDESCMSG, SNDSTSMSG, SNDCOMPMSG, or
SNDDIAGMSG such as:
C CALL 'SNDESC' TAA Tool
C PARM ZXMSDS Message ID
Or you could use the API (QMHSNDPM) that sends messages.
When system message handling support is used (also used by the TAA
Tools that were mentioned), the system formats the message text so
that a word is not split over a line.
If you are going to print the message, you could consider the TAA
Tool FMTLIN which can assist you in formatting the print lines so
that words are not split. See the discussion in the FMTLIN TAA Tool.
A message can be up to 512 bytes in length. For a multiple line
message, you would enter text such as:
U03 Complex message involving several lines
U03 of text. A blank will be added to each line.
U03 If you start a sentence with a new record, offset one byte.
You can concatenate 50 bytes of information on the end of the message
by just placing data (left adjusted in the ZXMCAT field such as:
C MOVEL'My value'ZXMCAT Concat area
A demonstration program exists:
You can display the source of the demonstration program to see how
the messages were sent. In the demonstration, the messages are sent
as diagnostic types by the TAA Tool SNDDIAGMSG.
You must leave the dummy array entry as the last record in the array.
If you request a Message ID that does not exist in the array, the
ZXMSDS area will contain appropriate text (see the demonstration).
The text is concatenated together to build the message. If you
concatenate more than 512 bytes, the data is just truncated (no error
You must use CPYTAA to copy the TAARPGJR member from the TAA Archive
to a normal source file where it can be used for the SEU copy
function. A typical solution would be to copy the TAARPGJR member to
the QATTRPG file in TAATOOL.
