[comp.os.cpm] Avoid clearing the screen after warmstart

UZR50D@DBNRHRZ1.BITNET (04/16/87)

Hi people,

I have an apple //e and whenever a CP/M - program is making a warmstart
after its execution my screen will be cleared.
But when this program for example displayed
a message or something else I can't read it anymore. So is there anybody
who can tell me (has a patch for CP/M (Vers. 2.2 56K or/and Vers. 2.3 60)
how one can avoid this behaviour of the CP/M - System?

In hope for a response  Ralf

Ralf, I don't think this is a CP/M problem.  I have used 60K Microsoft CP/M
2.23 on an oldstyle SoftCard in both a ][+ and a //e, and 64K PCPI CP/M 2.2 on
an Applicard, and I don't get this screen clearing that you describe.  Certain
programs from certain vendors may do it, but the following programs I've used 
don't, at least on my system:

	WordStar
	DataStar
	ReportStar
	MicroCalc
	Strunk & White
	Turbo Pascal
	Microsoft F80/M80/L80
	All the standard CP/M tools

Sorry I can't be more informative in a positive way, but I hope this will help
point you in the right direction.  Good luck in finding an answer.
