reemplazar un valor en una cadena caracteres

[Loren]

Compañeros, buenas tardes:

¿Sabeis la función que reemplaza un valor dentro de una cadena de caracteres?
Tengo una DBF con el campo NOMBRE,C,40
pero necesito hacer un barrido y cambiar todas las "A" del campo NOMBRE por "C"
algo así como
remplezar(nombre,"A","C")

Mil gracias.
LORENZO.

Lorenzo, si usas harbour tienes que enlazar hbct.lib
La funcion es Charrepl()
te dejo debajo como funciona

/* $DOC$
* $FUNCNAME$
* CHARREPL()
* $CATEGORY$
* CT3 string functions
* $ONELINER$
* Replacement of characters
* $SYNTAX$
* CHARREPL (<cSearchString>, <[@]cString>,
* <cReplaceString>, [<lMode>]) -> cString
* $ARGUMENTS$
* <cSearchString> is a string of characters that should be replaced
* <[@]cString> is the processed string
* <cReplaceString> is a string of characters that replace the one
* of <cSearchString>
* [<lMode>] sets the replacement method (see description)
* Default: .F.
* $RETURNS$
* <cString> the processed string
* $DESCRIPTION$
* The CHARREPL() function replaces certain characters in <cString>
* with others depending on the setting of <lMode>.
* If <lMode> is set to .F., the function takes the characters of
* <cSearchString> one after the other, searches for them in <cString>
* and, if successful, replaces them with the corresponding character
* of <cReplaceString>. Be aware that if the same characters occur
* in both <cSearchString> and <cReplaceString>, the character on a
* certain position in <cString> can be replaced multiple times.
* if <lMode> is set to .T., the function takes the characters in <cString>
* one after the other, searches for them in <cSearchString> and, if
* successful, replaces them with the corresponding character of
* <cReplaceString>. Note that no multiple replacements are possible
* in this mode.
* If <cReplaceString> is shorter than <cSearchString>, the last
* character of <cReplaceString> is used as corresponding character
* for the the "rest" of <cSearchString>.
* One can omit the return value by setting the CSETREF() switch to .T.,
* but then one must pass <cString> by reference to get the result.
* $EXAMPLES$
* ? charrepl ("1234", "1x2y3z", "abcd") // "axbycz"
* ? charrepl ("abcdefghij", "jhfdb", "1234567890") // "08642"
* ? charrepl ("abcdefghij", "jhfdb", "12345") // "55542"
* ? charrepl ("1234", "1234", "234A") // "AAAA"
* ? charrepl ("1234", "1234", "234A", .T.) // "234A"
* $TESTS$
* charrepl ("1234", "1x2y3z", "abcd") == "axbycz"
* charrepl ("abcdefghij", "jhfdb", "1234567890") == "08642"
* charrepl ("abcdefghij", "jhfdb", "12345") == "55542"
* charrepl ("1234", "1234", "234A") == "AAAA"
* charrepl ("1234", "1234", "234A", .T.) == "234A"
* $STATUS$
* Ready
* $COMPLIANCE$
* CHARREPL() is compatible with CT3's CHARREPL().
* $PLATFORMS$
* All
* $FILES$
* Source is charrepl.c, library is ct3.
* $SEEALSO$
* WORDREPL() POSREPL() RANGEREPL()
* CSETREF()
* $END$

Holas.... revisen esto:

cXx := "AHAHAHSHAHAHAH"
cXx := STRTRAN(cXx, "A", "C") // REEMPLAZA LA "A" POR LA "C"

? cXx -> CHCHCHSHCHCHCH

Como dice Willi, StrTran()
