KUPDATEB(argument,position <, n>, characters-to-replace)

Arguments

argument

specifies a character variable.

position

specifies the beginning character position in byte units.

n

specifies the length of the substring to be replaced in byte units.

Restriction:	n cannot be larger than the length (in bytes) of the expression that remains in argument after position.
Restriction:	n is optional, but you cannot omit both n and characters-to-replace from the function.
Tip:	If you omit n, SAS uses all of the characters in characters-to-replace to replace the values of argument.

characters-to-replace

specifies a character expression to replace the contents of argument.

Restriction:	characters-to-replace is optional, but you cannot omit both characters-to-replace and n from the function.
Tip:	Enclose a literal string of characters in quotation marks.

The KUPDATEB function replaces the value of argument with the expression in characters-to-replace. KUPDATEB replaces n byte units starting at the byte unit that you specify in position.
