I want to define default value for a field with length 3.
The field is inside a TDS message defined with its Physical Properties setting to "Fixed Length" for Data Element Separation.
I want to set a default value " ", that is 3 spaces.
But the issues, if I set " ", the whole message set is working but the default value 3 spaces are invisible.
So I would like to use mnemonics.
Based on the Message Model pdf book, it says:
<SP> X’20’ <U+0020> Space
These mnemonics were created for characters that cannot be entered into the
message editor.
You can enter a mnemonic in the form <U+NNNN>, where NNNN are hexadecimal
digits. None of the characters in this structure are case-sensitive. Do not enclose
spaces inside the angle brackets. These numbers represent a Unicode character, not
a character in the code page of the input message.
You can enter a mnemonic in the form <0xNN>, where NN are hexadecimal digits.
None of the characters in this structure are case-sensitive. Do not enclose spaces
inside the angle brackets. These numbers represent a raw hexadecimal byte value,
not a character in the code page of the input message.
If a mnemonic is of the form <0xNN>, it is applied directly to the input data, and no
code page conversion takes place. Otherwise, a mnemonic is applied to the data
after the data has been converted into Unicode from the code page of the input
data.
Default TDS message set propertie
I have tried <SP><SP><SP> and <0x20><0x20><0x20> and <U+0020><U+0020><U+0020>, but none of they are working.
Any help will be appreciated! |

Seems like this is tricky question.
So far the only thing I can say is the WMB or its document might not that reliable.
For example, when I filled in the Encoding Null Value by mistake, the WMB might tell me by deployment message saying :
Encoding Null Value must resolve to a single character when Encoding Null is NullLiteralFill for Element 'InvoiceSuffix'. Syntax is: SPACE, NUL, 0xYY, YY, U+xxxx, 'c', "c". Physical format: 'Text1'.
If I filled in with SPACE, can you image the result? All the Null Vlaue is filled with character 'S' rather than ' '. |

You seem to be quoting this
On the same page it says:
| Quote: |
| Mnemonics can be used in TDS properties Decimal Point, Escape Character, Reserved Characters, Delimiter, Group Indicator, Tag data Separator, Tag, and Repeating Element Delimiter to specify special characters |
I don't see where it says mnemonics are valid in the default value.
I also have to say I've never tried this & have no access at the moment to try this. Where I've had this situation I've put 3 spaces in the default and not worried that they can't be seen.

Thanks Vitor
I have changed the way for those null fields by outputing null value rather than default value.
But you post really makes sense to me. |
