[comp.sys.mac.programmer] Setting horizontal tabs on ImageWriter II

dtsai@uvicctr.UUCP (David Tsai) (08/04/88)

Hi netlanders:
	I am trying to print VMS/VAX text files through a MAC SE 
running the MAC 240 emulator to an ImageWriter II on a Apple Talk network.
My problem is that I cannot set the tab stops on the ImageWriter. 
( I have no problems with selecting fonts or type size using escape sequences.)
I have tried the following escape sequences but nothing worked.

	esc(9,15,..,125.
	esc(9,15,..,125,.
	esc(,9,15,..,125,.
	esc(,9,15,..,125.

The ImageWriter II Owner's Manual is of no help as there is no example 
on setting tab stops.  
The tabbing controls sequence listed in the IW II Quick Reference Card
is as follows:

Function		Keystrokes			Code
Set horizontal tabs	ESCAPE(a,b,n,...,.		27 40,n,n,n,...,46
			abn = column number through nth column

What is wrong with my escape sequence?  Any help is much appreciated.

Ken

I'm not sure about this, but you might try esc( followed by actual ASCII
characters with the code of the desired tabstop, as in "esc(abc" where "a"
"b" and "c" (actually, their ascii codes) represent the desired positions.

Oops!!!  
	I went out to a local book store this morning and found an
ImageWriter II programming manual which has lots of examples.
The correct syntax for horizontal tabs is 
	esc(009,015,...,071. for 80 columns  
  or    esc(009,015,...,131. for 136 columns.
I hurried back to work (on a Saturday!!) and got tabs stop going in 
no time.  The User Manual for the IW II from APPLE really sucks!!!

Sorry for the false alarm and please spare me from any RTFM message!! :-)
