DSC AND SCS DATA STREAM COMMANDS
A one-byte number that specifies the first print
line of the page
If tm is a positive number, but less than or equal
to the maximum page length (MPL), the value is
adopted as the top margin setting.
If tm is X'00' or nn is less than 3, defaults are
used for the top margin.
If tm is greater than MPL, defaults are used for
the top margin, bottom margin, and vertical tabs,
and a SCS parameter check results.
Default = 1
A one-byte number that specifies the last print
line of the page.
If bm is a positive number greater than or equal
to tm, but less than or equal to the maximum
page length (MPL), the value is adopted as the
bottom margin.
If bm is X'00' or nn is less than 4, the bottom
margin defaults to MPL.
If bm is less than tm or greater than MPL,
defaults are used for the bottom margin and
vertical tabs. An SCS parameter check results.
Default = maximum lines per page.
One-byte value that sets line number values for
both Vertical Tabs (VT) and Vertical Channel
Select (VCS) functions.
Tab values are valid if they are less than bm and
greater than or equal to tm; if this is not the
case, a SCS parameter check occurs.
If an error is found, tab processing stops and the
tab values last set remain unchanged.
If a tab value is zero, it sets no tab or channel
value.
tm is always the first tab value.
Default = each line from the top margin.
