KCVT Converts data from one type of encoding data toanother encoding data.
KINDEX Searches a character expression for a string of characters.
KINDEXC Searches a character expression for specified characters.
KLEFT Left-aligns a character expression by removing unnecessary leading DBCS blanks and SO/SI.
KLENGTH Returns the length of an argument.
KLOWCASE Converts all letters in an argument to lowercase.
KREVERSE Reverses a character expression.
KRIGHT Right-aligns a character expression by trimming trailing DBCS blanks and SO/SI.
KSCAN Selects a specified word from a character expression.
KSTRCAT Concatenates two or more character expressions.
KSUBSTR Extracts a substring from an argument.
KSUBSTRB Extracts a substring from an argument according to the byte position of the substring in the argument.
KTRANSLATE Replaces specific characters in a character expression.
KTRIM Removes trailing DBCS blanks and SO/SI from character expressions.
KTRUNCATE Truncates a numeric value to a specified length.
KUPCASE Converts all single-byte letters in an argument to uppercase.
KUPDATE Inserts, deletes, and replaces character value contents.
KUPDATEB Inserts, deletes, and replaces the contents of the character value according to the byte position of the character value in the argument.
