Delete

Description

Procedure Delete removes a substring from the specified source string.

PROCEDURE Delete(
				VAR source : DYNARRAY[] of CHAR;
				index      : INTEGER;
				count      : INTEGER);
def vs.Delete(source, index, count):
    return source

Parameters

Name Type Description
source DYNARRAY[] of CHAR Source string.
index INTEGER Start position in text string.
count INTEGER Length of substring.

Remarks

Per Raymond Mullin, on the VS list, there is a bug in Delete that prevents it from getting the last character if the string is a dynarray of char. The following test script should leave T = '', but it leaves T = '7'.

PROCEDURE DeleteTest;
VAR
T :DYNARRAY [] of CHAR;
BEGIN
T := '1234567';
Delete(T, 1, 7);
Message('T: ', T);
END;
RUN(DeleteTest);

Examples

VectorScript

theStr:='A sample string';
Delete(theStr,3,7);
{deletes 'sample' from the string value}

Python

def DeleteTest():
	T = '1234567'
	T = vs.Delete(T, 1, 7)
	vs.Message('T: ', T)

DeleteTest()
