How is Labelresponse.base64data defined?
Is it defined VARCHAR(4096) CCSID(1208)?
Is it CHAR with trailing whitespace?
Did you try to trim it?
To do base64 decoding, I normally use base64_decode from Scott Klement's BASE64R4 module.
Looks like the input to systools.base64decode must be:
"A character string in CCSID 1208 that is currently Base64 encoded. The length cannot exceed 4096 characters."

Subject: Base64Decode
Hi All
This is the first time I am working the a Base64 returned value from a web service.
It's the shipping label from a carrier.
When I use Labelary, paste in value and decode it show the label as expected.
Where I am having issues is in the exec sql set :DecodedLabel = systools.base64decode(:Labelresponse.base64data)
Either I get nothing in the DecodedLabel or not ZPL type data.
I have tried several different combinations of CCSID (including nothing) on the DecodedLabel but just not working.
Dcl-S DecodedLabel VarChar(4096) CCSID(1208);
What is the obvious thing I am doing wrong?
