MID$
Abbreviation: M <SHIFT+I>
TYPE: String Function
FORMAT: MID$(<string>,<numeric-1>[,<numeric-2>])
Action: The MID$ function returns a sub-string which is taken
from within a larger <string> argument. The starting position
of the substring is defined by the <numeric-1> argument
and the length of the sub-string by the <numeric-2> argument.
Both of the numeric arguments can have values ranging from 0 to
255.
If the <numeric-1> value is greater than the length of
the <string>, or if the <numeric-2> value is zero,
then MID$ gives a null string value. If the <numeric-2>
argument is left out, then the computer will assume that a length
of the rest of the string is to be used. And if the source string
has fewer characters than <numeric-2>, from the starting
position to the end of the string argument, then the whole rest
of the string is used.
EXAMPLE of MID$ Function:
10 A$="GOOD"
20 B$="MORNING EVENING AFTERNOON"
30 PRINT A$ + MID$(B$,8,8)
GOOD EVENING
