Hi,
An IMS transaction written by PL/I sents me an EBCDIC message that contains a field called PRODUCT_COUNT with the value of "F0F0F0F1" (ascii: 0001, meaning only one product found).
Here is the field defination:
PRODUCT_COUNT PIC '9999', /* NUMBER OF PRODUCTS */
I tried to define this field in my message set with CWF (too late to change it back to TDS) with the following:
Logical type = xsd:short
Physical type = External Decimal:
Length = 4 bytes
The rest of properties are default.
But when I turned on debugger, I saw a big interger number other than 1 which is i am expecting to see...
What am I missing here?
Thanks,
James |

Not used PL/1 for 20 years, but isn't that picture a numeric character? Certainly 'F0F0F0F1' is '0001' is EBCDIC unless I'm much mistaken (and could be). So xsd:short is going to interpret it as a really big number surely?

I tried a number of types with logical, physical etc...
Now I am tired and I just wanted to know how to configure this in MS?
Many many thanks! |

| Oh, by the way, only if I cahnged to xsd:string, then it shows '0001' in memory tree which is what I want... But I hate to alter the type to string every this kind of field. |

It's a hard life, and I recommend a caffinated beverage...
Well I've offered my guess; shame you've tried that & it didn't work!

| I learnt PL/I many years ago. PIC '9999' is just character representation of a numeric value (with leading zeros included). |

Which is what I'd expect - PIC 9 represents numeric character. Like I said.

You should be able to tell the model to read this value as a number and interpolate the characters into an integer. This should be straight forward.
If you are getting a high value number when you expect a low value number, then you have the wrong endianness on the message definition element. |
