Delete string


Delete string ( source ; where ; numChars ) -> Function result

Parameter	Type	Description
source	String	String from which to delete characters
where	Longint	First character to delete
numChars	Longint	Number of characters to delete
Function result	String	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
