哪里错了

为什么分开执行时可以呢？

function f_xj(s)//新建文件
return create_file(s)
endf
function f_qk(s)//清空文字内容
variablefe = fopen(s, "w","UTF-8")
fprintf(fe,"%s","")
fclose(fe)
endf
function f_storage_f(s,str)
variable fp=fopen(s,"a","UTF-8")
fprintf(fp,"%s\n",str)
fclose(fp)
endf

如果，文加行号_new.mfps中出错了，要增加或减少行数，怎样将"//第1"这样的文字去掉，重新编排，加行数

有三种格式需变动，
①第21行：文尾去掉 "☞第21"
②第1~9行：文尾去掉"//☞第1"~"//☞第9"
③第10~20行及第22行：文尾去掉"//☞第10"~"//☞第20"及"//☞第22"
①中无"//"
②③字符长度不同
得用3个if

if <1>//☞第21
variable h=split(str,"☞")
取h[0]
elseif <2>//第1~20,第22
variable g=split(str,"//")
取g[0]
endif

fprintf(fa,"%s\n",split(str," ☞")[0])
endif
