我想用VB做个数据自动生成的软件，当输入行数为10，字段数为4，起始号为1，跳数为10，位数为4，前缀AA，后缀BB，点生成数据。   自动生成写入到文本。文本内容如下：
AA0001BB,AA0011BB,AA0021BB,AA0031BB
AA0002BB,AA0012BB,AA0022BB,AA0032BB
AA0003BB,AA0013BB,AA0023BB,AA0033BB
AA0004BB,AA0014BB,AA0024BB,AA0034BB
AA0005BB,AA0015BB,AA0025BB,AA0035BB
AA0006BB,AA0016BB,AA0026BB,AA0036BB
AA0007BB,AA0017BB,AA0027BB,AA0037BB
AA0008BB,AA0018BB,AA0028BB,AA0038BB
AA0009BB,AA0019BB,AA0029BB,AA0039BB
AA0010BB,AA0020BB,AA0030BB,AA0040BB
