Hello,
 
I am using GRETL 1.9.9 on a Win 7 64bit machine. I found a quirk that may be a bug. I found that
 
bundle BundleOfMatrixs
matrix BundleOfMatrixs["test"] = {}
matrix test = {1,2,3,4}
BundleOfMatrixs["test"] |= test
 
yields the following error message
 
'|=' : only defined for matrices
 
Error executing script: halting
> BundleOfMatrixs["test"] |= test
 
but  that
 
bundle BundleOfMatrixs
matrix BundleOfMatrixs["test"] = {}
matrix test = {1,2,3,4}
BundleOfMatrixs["test"] = BundleOfMatrixs["test"]|test
 
works just fine.
 
Thanks.
