Expand description
§[LET] MID$(<string>,n[,m])=<expression>
§Purpose
Assign the result of expression to variable.
§Remarks
The word LET is optional. Replaces part of the string
beginning at position n with expr. The string will not
change size so extra chars from the expr are ignored.
The length of expr used may be limited by the optional m.
§Example
A$(5)="PORTLAND, ME"
LET MID$(A$(5),11)="OR"
PRINT A$(5)
PORTLAND, OR
