MID$ Statement
MID$(oldstring,start[ ,length]) = newstring
Replaces a portion of oldstring with newstring.
Oldstring
is the variable name of the string you want to change.
Start is a number specifying the position of the first character
you want
to change.
Length is a number specifying the number of characters you
want
to replace.
Newstring is the string to replace a portion of oldstring.
The length of the resultant string is always the same as the
original string. If
newstring is shorter than length, the entire re-
placement string is used.
Examples:
10 FIB = "LINCOLN"
20 MID$CAB,3,4) = "12345": PRINT AB
prints LI1234N.
Replace Line 20 with:
20 MIDB<FIB,S) = "01": PRINT A$
and BASIC prints LINC01N
