## Strings

 Function Description Len(s) Length of a string Char(s, i) Returns a character from the string s at index i. Characters are indexed starting at 0.

## Data Type Conversion

 Function Description ToChar(n) Convert a character code n into a character. ToCode(c) Convert a character c into a character code (integer). ToFixed(r, i) Convert real number r to a string with i digits after the decimal point. This function is useful for currency. ToInteger(n) Convert a string to an integer ToReal(n) Convert a string to an real ToString(n) Convert a number to a string

## Other
