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.
