Text String Processing Instructions Section 3-33
The maximum number of characters to be read that can be designated by S2
is 4,095 (0FFF hex). If more than that are designated, an error will be gener-
ated and the Error Flag will turn ON.
If 0 (0000 hex) is designated as the number of characters to be read, the two
NUL characters (0000 hex) will be output to D.
If 0000 (hex) is output to D, the Equals Flag will turn ON.
Example In this example, MID$(654) is used to read three characters.
