assistant: Hello Keith!
Replying to a message of Keith Douglas to John Meroth:
To display a char on a CLI screen takes but two CPU instructions.
To display that same char on a graphics screen can take many times more.
I suspect that it would be dialect dependant as a WP that handles SS data has
to first be able to understand that data in order for it to be able to
dynamically updated. (i.e. update the spreadsheet and the report written in
the word processor will show the update.
Judgement call and very hardware dependent. On my BBS system whis is still a
486, the difference is dramatic.
On this system that is a P120 with an accelerated video card, the difference
is not so obvious.
In a company with 20 workstations, upgrading to pentiums with accelerated
video cards just so they can run GUI applications at nearly the same speed
that they get with a good CLI program now is not worth the expense.
Contrary to what you may read here, MOST businesses still use DOS for the
data entry/WP tasks.
Don't confuse the simplicity of a high level instruction with what the CPU
has to do with that instruction. Drawstring() would still take many more CPU
instructions than printf()
The operative word was RICH. That has no bearing on ASCII
It is. The data is stored in FILES.BBS
TTYL,
John Meroth
