May I ask why you convert the sublist in an array? (If I understood the operations of your code)

If I understood correctly you go through the list of variables in a subdirectory. If a variable has an acceptable name, then it should be a list in the form:
{ 274.74 38.00 14.00 8.00 }
then you convert it to a vector with AXL and that is where I am puzzled.
Couldn't you just sum the elements in a list? With \GSLIST or sigmaList (left shift, SYMB [the MTH menu], list, sigmaList)

I stumbled across one "bug" in \GSLIST. I have had on occasion lists that purely have one value, such as {216.30} 'AUG07' STO. \(\sum\)LIST barfs on lists that only have one entry and complains "Invalid Dimension", AXL CNRM steps around this problem nicely.
