DSC AND SCS DATA STREAM COMMANDS
lm
(continued) A one-byte number that specifies the column
value of the left most print position.
If lm is a positive number but less than the
maximum print position (MPP), the value is
adopted as the left margin setting.
If lm is X'00' or nn is less than X'03,' defaults are
used for the left margin.
If lm is greater than MPP, defaults are used for
the left margin and horizontal tabs and a SCS
parameter check occurs.
LM defaults to column 1 if not given, so default
= X'01.'
rm A one-byte number that specifies the column
value of the right most print position.
If rm is a positive number greater than or equal
to lm, but less than the maximum print position
(MPP), the value is accepted but not used.
If rm is less than lm or greater than MPP, defaults
are used for the right margin and horizontal tabs
and a SCS parameter check occurs.
RM defaults to MPP if not given, so default =
maximum print position.
ht1...tn One-byte number that sets the column number
for horizontal tabs.
Tab values are valid if they are less than the
maximum print position (MPP) and greater than
or equal to lm.
If this is not the case, no tabs are set and a SCS
parameter check occurs.
If a tab value is zero it is not set.
The first tab value is lm and the default is a tab at
each character space from the left margin.
Remember •This command must be initialized by a new line or a carriage
return or the old values are used.
•The maximum number of tabs is 251.
•If the command is received on a page boundary, the page
dimensions are recalculated, possibly changing the page
orientation.
