Error Flag ER
Equals Flag =
The maximum number of characters for S1 and S2 is 4,095 (0FFF hex). If
there are more than that (i.e., if there is no NUL before the 4,096th character),
an error will be generated and the Error Flag will turn ON.
The range for the beginning position designated by S3 is 0 to 4,095. If the set-
ting is outside of this range, an error will be generated and the Error Flag will
turn ON.
If 0000 (hex) is output to D, the Equals Flag will turn ON.
Do not overlap the destination words designated by D with the text string data
designated by S2. If these overlap, the operation will not be executed properly.
In this example, INS$(657) is used to insert two characters.
