Text String Processing Instructions Section 3-33
The range for the beginning position designated by S4 is the 1st to the
4,095th character (0001 to 0FFF hex). If the setting is outside of this range, an
error will be generated and the Error Flag will turn ON.
If the beginning position designated by S4 is beyond the text string designated
by S1, 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.
Set the first destination word D so that it does not overlap with the areas set
with the replacement text string first word S2. RPLC$(654) will not work cor-
rectly if these areas overlap.
Example In this example, RPLC$(654) is used to read three characters.
