pack D. zap 相关知识点: 试题来源: 解析 D 在FoxPro中,各选项功能如下: - **A. delete**:仅给记录打上删除标记,不会物理删除,需配合PACK才能彻底删除。 - **B. recall**:用于恢复被标记为删除的记录,与题意完全相反。 - **C. pack**:物理删除已标记为删除的记录,但需先通过DELETE标记所有记录后...
2. **PACK**:该命令会永久移除所有带有删除标记的记录,并压缩表文件,实现彻底删除。 3. **ZAP**:此命令直接清空整个表的所有记录(无论是否有删除标记),与题目要求的“仅删除有删除标记的记录”不符。 4. **RECALL**:用于撤销记录的删除标记,功能完全相反。 综上,正确答案为 **B.PACK**。
