Function: substring()
Returns a portion of the supplied string between specified character positions.
Syntax
substring(string, startPosition, endPosition)
| Argument | Type | Description |
|---|---|---|
| string | String | The string to be processed. |
| startPosition | Integer | The character position to start the substring from. |
| endPosition | Integer | The character position to end the substring at. If not specified, the substring will default to the end of the string. |
Examples
substring("01223236023",6,9)
Returns the portion of the string between character positions 6 and 9: "2360".
substring("01223236023",6)
Returns the portion of the string between character position 6 and the end of the string: "236023".
substring(in.fileName, indexOf(in.fileName, "_")+1, indexOf(in.fileName, "_")+9)
Suppose in.fileName contained file names with the format "switchRC48_20060708.exp" and we wish to retrieve the date from the file name.
The first, string portion of the file name is variable so we search for the "_" character with the function indexOf, and use the returned value in substring to pull out the date from the file name.
