Description
Replace string replaces howMany occurrences of oldString in source with newString.
If newString is an empty string (""), Replace string deletes each occurrence of oldString in source.

If oldString is an empty string, Replace string returns the unchanged source.
Examples
1. The following example illustrates the use of Replace string. The results, described in the comments, are assigned to the variable vtResult.
vtResult:=Replace string("Willow";" ll";"d") ` Result gets "Widow"
vtResult:=Replace string("Shout"; "o";"") ` Result gets "Shut"
vtResult:=Replace string(vtOtherVar;Char(9);",") ` Replaces all tabs in vtOtherVar with commas
2. The following example eliminates CRs and TABs from the text in vtResult:
vtResult:=Replace string(Replace string(vtResult;Char(13);"");Char(9);"")
