When handling strings, nuBASIC uses the set of ASCII characters. The Asc and Chr functions allow the ASCII value belonging to a character to be established and/or the corresponding character to be found for a ASCII value. Example: Print Asc("A") 65 Print Chr(65) A The Chr function is often used in Basic languages to insert control characters in a string. The following assignment MyString$ = Chr (9) + "Hello World" + Chr(13) nuBASIC provides the InStr function for searching for a partial string within another string. Example: ResultString% = InStr(MyString$, SearchString$) The SearchString$ parameter specifies the string to be searched for within MyString$. The function returns a number that contains the position at which the SearchString$ first appears within MyString$ or -1 otherwise. InStr ignores uppercase and lowercase characters.InStrCs is the case sensitive version of InStr. nuBASIC provides several functions that return partial strings, plus a length function: |
