[Help-gsl] General CBLAS question

I looked for this in the GSL docs, but maybe it is too basic.
I also looked at the source, but I must be missing something.
Anyways, many CBLAS functions calculate something like
y = a A x + b y.  I need (and have tried) the following which
seems to work: y = 1 A y + 0 y.  Is that OK or will you run
into trouble somehow.  Any pointers welcome.  Thanks
