ReplaceA DataWindow expression function

Description

Replaces a portion of one string with another.

Syntax

Argument	Description
string1	The string in which you want to replace bytes with string2.
start	A long whose value is the number of the first byte you want replaced. (The first byte in the string is number 1.)
n	A long whose value is the number of bytes you want to replace.
string2	The string that replaces bytes in string1. The number of bytes in string2 can be greater than, equal to, or fewer than the number of bytes you are replacing.

Return Values

String. Returns the string with the bytes replaced if it succeeds
and the empty string (“”) if it fails.

Usage

If the start position is beyond the end of the string, ReplaceA appends string2 to string1.
If there are fewer bytes after the start position than specified
in n, ReplaceA replaces
all the bytes to the right of character start.

If n is zero, then in effect ReplaceA inserts string2 into string1.

ReplaceA replaces the functionality that Replace had
in DBCS environments in PowerBuilder 9. In SBCS environments, Replace and ReplaceA return
the same results.
