st: weird "labels.Arrpush" error in -scatter-

["Feiveson, Alan H. (JSC-SK311)" <alan.h.feiveson@nasa.gov>]

Hello everyone - 

Has anybody had this occur in Stata 9 (Windows)?

Apparently if a variable label starts with "=", -scatter- gives an
"Arrpush" error. The error only seems to occur if the "=" is the first
character in the label (see below).



. des b time

              storage  display     value
variable name   type   format      label      variable label
------------------------------------------------------------------------

b               float  %9.0g                  =EQ/100
time            float  %9.0g                  raw time (days)

. scatter b time

. label var b "xyz"

. scatter b time   [works]

. label var b "=EQ/100"

. scatter b time

r(198);

. label var b "=www"

. scatter b time
labels.Arrpush invalid name

r(198);


. label var b "w=ww"
. scatter b time       [works]

On the other hand, the old graphics (-graph7) is not bothered by this.

. label var b "=www"
. graph7 b time   [works]
