| I have a situation where I have a message coming in with a string valued at low-values. I check my input for spaces and if not spaces populate the output field. I do not want to send the low values. Is there a way to check for low values? I tried Casting the string to blob but the cast fails as it does not consider low values a valid character. Does anyone know of a way around this? My second problem is that I want to put an end of file indicator of high values on an output message for a smalltalk app. to read. I tried the same thing. I created a hldarea blob then tried to cast it as character and received an error again. If anyone knows how to handle these special characters in MQSI your help would be greatly appreciated. Thanks, Karen Welch |

For the input, can you check for null or spaces.
For the output, after you've built the output message pass it though an RCD node to make it a BLOB. In a Compute, you can then concatenate a x'ff' at the end because you're working in binary at this point.
Cheers

I do check the input for spaces and did try checking for null but it does not meet that criteria because something is there and that something is not spaces. That is why I tried to cast the field to blob so I could check for x'00' but it fails on the cast.
I will try your suggestion on the output though. Thanks.

IF InputBody.e_Field1 = '' THEN
SET OutputRoot.XML.Top.Field1 = 'Nulls12345';
ELSE
SET OutputRoot.XML.Top.Field1 = InputBody.e_Field1;
END IF;
IF InputBody.e_Field2 = ' ' THEN
SET OutputRoot.XML.Top.Field2 = 'Spaces7890';
ELSE
SET OutputRoot.XML.Top.Field2 = InputBody.e_Field2;
END IF;
Cheers.

Hi gaussspg,
We could not get the IS NULL to work. We had to check for '' and this worked but now with WMQI 2.1 CSD2 we found that the '' does not work either unless you have your padding character defined as NUL instead of SPACE on the field in your messageset. Lucky for us we don't use this particular Message as output or we would be in trouble because we really want our string fields to be padded with spaces.
