示例1: CONSTLIT
ICCItem *fnSubst (CEvalContext *pCtx, ICCItem *pArguments, DWORD dwData)
// fnSubst
//
// Substitutes string parameters
//
// (subst string arg1 arg2 ... argn)
{
CCodeChain *pCC = pCtx->pCC;
ICCItem *pArgs;
// Evaluate the arguments and validate them
pArgs = pCC->EvaluateArgs(pCtx, pArguments, CONSTLIT("s*"));
if (pArgs->IsError())
return pArgs;
CString sPattern = pArgs->GetElement(0)->GetStringValue();
// Do the substitution
char szResult[4096];
char *pPos = sPattern.GetASCIIZPointer();
char *pDest = szResult;
