how to know the last printed text in QBasic -


i want know how last printed text in qbasic. if program prints several lines, how last line printed.

like this-

print "aaaaaaa" print "bbbbbbb"

then program last printed line i.e. bbbbbbb

something maybe?

str$ = "aaaaaaa" print str$ str$ = "bbbbbbb" print str$ print "last printed line:"; str$

alternatively, explained here, can retrieve characters screen memory using peek @ segment &hb800 , this

def seg = &hb800 mychar = peek(1) 'etc

you'd have keep track of on line last printed know need peek, complicated quickly...

for reason recommend rethink trying accomplish here because "screen scraping" bad idea.
