Parameters
| Parameter | Description |
|---|---|
| source | The string to be changed. |
| from | The start index in the "source" string from which the content shall be replaced/inserted, beginning with 0. |
| count | The number of digits from the start index to be replaced in "source". Note that you specify the exact length of the string to be replaced. |
| replace | String that should be replaced/inserted. |

Description
Changes the content of a string at a specific index for a defined count of digits with a replacing string.
The string "source" is changed by inserting the string "replace" at the index "from" and replacing a "count" of digits.
A "count" of 0 only inserts the string "replace" at the index "from" without replacing other digits.
uniStrChange() can also be used to insert/append the string "replace" at the beginning or the end of the string "source". The value for "from" must be 0 for inserting at the beginning or must be the length of "source" ("from" = strlen(source)) for inserting at the end. To prevent digits of being replaced a "count" value of 0 is necessary.
Example
Changes the content "ETM Professional Control, A Siemens Company" to ETM Professional Control, A Siemens Компания.
main()
{
/* uniStrChange changes the content of a string by changing a
specific number
of characters at a given position */
int d;
string so= "ETM Professional Control, A Siemens Company";
unsigned fr = 36;
unsigned co = 7;
string re = "Компания";
d = uniStrChange(so, fr, co, re);
DebugN("Return value:", d, "Changed content:", so);
