TOKEN
var := TOKEN [ /S ] [ /D=delimiter ] /- index string1 string2
-> var = 'token' or empty if index is not a number or outside the range 0 .. nTokens-1
This command, similar to the WORD command, tokenises a string using blanks, or the specified delimiter.
When using TOKEN, do not forget to use the "/-" option before the first argument (and after any other options). Without the "/-" option, any argument starting with a slash will be mistaken for an option.
- index
- The zero-based index of the word to return (0 <= index <= nWords-1).
- string1, string2
- A string to tokenise.
- /S
- If set, the function sets the return code on failure. Otherwise, it sets the return code to 0, even if the parameters are invalid.
- /D
- Set the delimiter using the following format:
- /D=delimiter
- E.g.:
- var := token /D=, /- $#index $#wordlist
- The default delimiter is a blank.
Example:
#str := set 'to be, or not to be, that is the question' #var := token /D=, /- 1 $#str um The second comma separated value in the string "$#str" is "$#var" // will return ' or not to be'
