MC-Basic:MID$

The MID$ function returns the specified number of characters from the string, starting at the character at position <start>. If <start> is greater than the length of <string>, the returned <string> is empty.

In UTF-8 supporting versions 4.5.1 and higher NULL characters are no longer cut

out from strings, resulting in a different behavior:

The string resulting from concatenation is composed from 'A\0B', i.e., there is a NULL character in the MIDDLE of the string:

Display cuts the string in the middle NULL:

-->?"A" + Chr$(0) + "B"

A

Mid$ gives NULL for the second character:

-->?Mid$("A" + Chr$(0) + "B", 2, 1)

-->

Value of Len is 3:

-->?Len("A" + Chr$(0) + "B")

3.000000000000000e+00

Len of Chr$(0) is 1:

In former versions NULL characters could not appear in the middle of strings, since

theconcationation process cut these characters from the resulting string.
