Delete string
Delete string ( source : Text ; where : Integer ; numChars : Integer ) : Text
| Parameter | Type | Description | |
|---|---|---|---|
| source | Text | → | String from which to delete characters |
| where | Integer | → | First character to delete |
| numChars | Integer | → | Number of characters to delete |
| Function result | Text | ← | Resulting string |
Description
Delete string deletes numChars from source, starting at where, and returns the resulting string.
Delete string returns the same string as source when:
- source is an empty string
- where is greater than the length of source
- numChars is zero (0)
If where is less than one, the characters are deleted from the beginning of the string.
If where plus numChars is equal to or greater than the length of source, the characters are deleted from where to the end of source.
Example
The following example illustrates the use of Delete string. The results are assigned to the variable vtResult.
vtResult:=Delete string("Lamborghini";6;6) // vtResult gets "Lambo"
vtResult:=Delete string("Indentation";6;2) // vtResult gets "Indention"
vtResult:=Delete string(vtOtherVar;3;32000) // vtResult gets the first two characters of vtOtherVar
