I have a field which is 65 characters in length and contains codes in brackets as follows:- (A), (B), (C) and so on.
These can appear in any part of the field. Is there a quick way of deleting these codes. I would normally do it manually but there are over 2000 records.

My FP 2.6 is a little =rusty but this should work.

CODE

USE DBF
GOTO TOP
SCAN ALL
    lcString = ALLTRIM(FIELD)
    lcString = Parse(lcString , "(" , '')
    lcString = Parse(lcString , ")" , '')
    ..... any other char you want stripped out

    REPLACE FIELD WITH lcString

ENDSCAN

CLOSE DATA

FUNCTION Parse
PARAMETER pcString, pcChar, pcWith
SET STEP ON
llDoit = .t.
DO WHILE llDoIt = .T.
    lnLen = LEN(pcString)
        lnLoc = AT(pcChar,pcString)
    DO case
    CASE lnLen = 0
        llDoIt = .F.
    CASE lnLoc = 0
        llDoIt = .F.
    CASE lnLoc = 1
        pcString = SUBSTR(pcString,2)
    CASE lnLoc > 0
        lcFst = SUBSTR(pcString,1,lnLoc-1) + pcWith + SUBSTR(pcString,lnLoc+1)
    ENDCASE
ENDDO
RETURN pcString

philthoms,
not fully clear your wish.
Show examples old and new fields.
Meanwhile see strtran() or stuff().

Sorry Forgot to change a Memvar name

lcFst = SUBSTR(pcString,1,lnLoc-1) + pcWith + SUBSTR(pcString,lnLoc+1)

should be

lcString = SUBSTR(pcString,1,lnLoc-1) + pcWith + SUBSTR(pcString,lnLoc+1)

My Memory is getting older then version 2.6, Did Strtran() and Stuff() exist in version 2.6 ???

I answered this question in another forum.

REPLACE ALL ;
  field with strtran(field,"(A)",""),;
  field with strtran(field,"(B)",""),;
  field with strtran(field,"(C)",""),;

just go on until the command line limit. That will do it in one pass without looping code.
