CONVERTSTR
Function (STRING)
CONVERTSTR
Function is used to converts some characters in a string.
NewString := CONVERTSTR(String,
FromCharacters, ToCharacters)
·
The
characters in the FromCharacters parameter are
replaced by the characters in the ToCharacters
parameter.
·
A
run-time error occurs if the lengths of the FromCharacters
and ToCharacters strings are not equal.
·
If
either the FromCharacters or the ToCharacters strings are empty the source is returned
unchanged.

Example
OriginalString := 'Want
to leave without saving?'
FromChars := ‘lws’
ToChars := ‘LWS’
NewString := CONVERTSTR(OriginalString, FromChars, ToChars);
MESSAGE (OriginalString); -> Want to leave without saving?
MESSAGE(NewString); -> Want
to Leave Without Saving?
COPYSTR
Function (STRING)
COPYSTR function
is used to copies a substring of any length from a specific position in a
string (text or code) to a new string.
NewString := COPYSTR(String, Position
[, Length])
·
If
you omit Length, the resulting string includes all
the characters from Position to the end of the
string.
·
If Position is less than 1 or Length
is less than 0, an error is returned.
·
If Position is beyond the length of the current string, an
empty string is returned.
·
If Position combined with Length
exceeds the length of the string, all the characters from Position to the end of the string are returned.
Example
Str := 'Using the COPYSTR function';
Position := 7;
Length := 8;
NewStr := COPYSTR(Str, Position, Length);
MESSAGE(Str); -> Using the COPYSTR function
MESSAGE(NewStr); -> the COPY
