Set Left Margin and Tabs 

for Diablo 1610-compatible
daisywheel printers


SLMT is a further development of SLM (Set Left Margin).  It has a 
single command, SLMT n, where n is the column in which you wish 
to set the left margin.  It then clears any previously set tab 
stops and sets nine new ones at standard eight-column intervals.

It does not clear any other printer features, so the tabs will 
set correctly for 12 or 15 pitch if the pitch has been set before 
running SLMT.  Owing to a peculiarity of the printer, however, 
the margin is always set to the 10 pitch scale, even if the 
printer has been switched to 12 or 15 pitch, so you will have to 
make allowance for that.

I wrote this program to use with Eric Meyer's VDE, which does not 
expand so-called real tabs (^I or 09h) in the nondocument mode, 
making it difficult to print out source code files unless I ran 
them through FILT7 to translate all tabs to spaces. Since the 
printer initialization string in my copy of VDE is empty, it 
doesn't conflict with SLMT. Other printing programs which do 
initialize the printer may however undo the margin and tabs set 
by SLMT.  Unfortunately there's nothing SLMT can do about that.

I am including a Z33 version, SLMT.CIM, which has been assembled 
to run in high memory at 9800h in a ZCPR v3.3 environment. This 
allows you to quit VDE, run SLMT, and restart very quickly with 
GO <fn.ft>.  This version will not work in a Z3 or any other non- 
Z33 environment.

Incidentally, to test SLMT you can print the Z80 source file in 
this library, as it uses real tabs rather than spaces.
