Text String Processing Instructions Section 3-33
Description RPLC$(661) replaces part of the text string designated by S1, from the begin-
ning position designated by S4, with the text string designated by S2, and out-
puts the result to D as text string data (with NUL added at the end). The
number of characters to be replaced is designated by S3.
The maximum number of characters in the result is 4,095 (0FFF hex). If the
number is greater than that, only 4,095 characters will be output (with NUL
added as the 4,096th).
From 0 to 4,095 characters (0000 to 0FFF hex) can be replaced. If the number
is 0, then the text string designated by S1 will be output to D just as it is, with
no change. If the S2 text string is NUL, then the operation will be the same as
deleting the designated range of text in S1.
If the S1 text string from beginning to end is replaced by NUL, then two NUL
characters (0000 hex) will be output to D.
Flags
Precautions The maximum number of characters for S1 or 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 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.

Error Flag ER ON if more than 4,095 characters are designated by S1
or S2.
ON if more than 4,095 characters (0FFF hex) are desig-
nated by S3.
ON if the S4 data is within the range of 1 to 4,095 (0001
to 0FFF hex).
OFF in all other cases.
