HOR_MAGNIFY, HMAG
Command/Query
The HOR_MAGNIFY command horizontally expands the se-
lected expansion trace by a specified factor. Magnification factors
which are not within the range of permissible values will be
rounded to the closest legal value.
If multiple zoom is enabled, the magnification factor for all expan-
sion traces is set to the specified factor. If the specified factor is too
large for any of the expanded traces (depending on their current
source), it is reduced to an acceptable value and only then applied
to the traces.
The VAB bit (bit 2) in the STB register (Table 8, page 137 ) is
if a factor outside the legal range is specified.
The HOR MAGNIFY query returns the current magnification
factor for t’he specified expansion function.
<exp_trace>:Hor_MAGnify <factor>
<exp_trace> := {EA, EB, MC*, MD*}
<factor> :=
9410/14 All others
1 to 200 I to I000
<exp_source>: Hor_MAGnify?
<exp_source>:Hor_MAGnify <factor>
The following example horizontally magnifies Expand B (EB) by
factor of 5.
