| | Command | Purpose | Example | | | Command | Purpose | Example | |
| | ''→STR'' | Convert to string | ''45,569 →STR'' yields ''"45,569"'' | | | ''→STR'' | Convert object to string | ''45,569 →STR'' yields ''"45,569"'' | |
| | ''STR→'' | Convert from string to implied object((In this case, ''OBJ→'' can also be used.))| ''"45,569." STR→'' yields ''45.569.'' | | | ''STR→'' | Compile a string to RPL objects((In this case, ''OBJ→'' can also be used.))| ''"45,569." STR→'' yields ''45.569.'' | |
| | ''→NFC'' | Convert to NFC | ''"Hello World" →NFC'' yields ''"Hello World"''| | | ''→NFC'' | Normalize a string to Unicode NFC | ''"Hello World" →NFC'' yields ''"Hello World"''| |
| | ''UTF8→'' | Convert each character in string to Unicode UTF8 object | ''"abcd" UTF8→'' yields ''{ #61h #62h #63h #64h }'' | | | ''UTF8→'' | Convert string to list of Unicode Code Points | ''"abcd" UTF8→'' yields ''{ #61h #62h #63h #64h }'' | |
| | ''→UTF8'' | Convert list of Unicode UTF8 objects to a string | ''{ #61h #62h #63h #64h } →UTF8'' yields ''"abcd"''| | | ''→UTF8'' | Convert list of Unicode Code Points to a UTF8 string | ''{ #61h #62h #63h #64h } →UTF8'' yields ''"abcd"''| |
| | ''SIZE'' | Return the number of characters in a string | ''"Hello World" SIZE'' yields ''11''| | | ''SIZE'' | Return the number of bytes used by a UTF8 string | ''"Hello World" SIZE'' yields ''11''| |
| | ''STRLEN'' | Returns the length of the string, in characters | ''"Hello World" STRLEN'' yields ''11'' | | | ''STRLEN'' | Returns the length of the string, in characters | ''"Hello World" STRLEN'' yields ''11'' | |
| | ''STRLENCP'' | Returns the length of the string, in characters | ''"Hello World" STRLEN'' yields ''11'' | | | ''STRLENCP'' | Returns the number of Unicode Code Points in a string | ''"Hello World" STRLEN'' yields ''11'' | |
| | ''POS'' | Returns the position of a substring within a string (0 if not found) | ''"Hello World" "Wor" POS'' yields ''7''| | | ''POS'' | Returns the position of a substring within a string (0 if not found) | ''"Hello World" "Wor" POS'' yields ''7''| |
| | ''POSREV'' | Returns the position of the substring counting from end of sting (0 if not found) | ''"Hello World" "Wor" POSREV'' yields ''3'' | | | ''POSREV'' | Returns the position of the substring counting from end of sting (0 if not found) | ''"Hello World" "Wor" POSREV'' yields ''3'' | |
| | ''NPOS'' | | | | | ''NPOS'' | Same as ''POS'', but starting the search from position N | | |
| | ''NPOSREV'' | | | | | ''NPOSREV'' | Same as ''POSREV'' starting at position N | | |
| | ''SREV'' | Reverse the string | ''"Hello World" SREV'' yields ''"dlroW olleH"'' | | | ''SREV'' | Reverse the string | ''"Hello World" SREV'' yields ''"dlroW olleH"'' | |
| | ''REPL'' | Replace part of a string with another at the specified position | ''"Hello World" 7 "Universe" REPL'' yields ''"Hello Universe"''| | | ''REPL'' | Replace part of a string with another at the specified position | ''"Hello World" 7 "Universe" REPL'' yields ''"Hello Universe"''| |
