Question

将大约 80 KB 的大文件的内容分配给字符串变量

copy-lob from file "E:\edifact\test\22685.EDI" to text-memptr.
v-edistring  = get-string(text-memptr,1).

shows error attempt to exceed maximum size of character variable.

Answer 1

你真的需要内存指针吗？否则，您可以直接将 COPY-LOB 复制到 LONGCHAR 中。

DEFINE VARIABLE cString AS LONGCHAR   NO-UNDO.

COPY-LOB FROM FILE "E:\edifact\test\PFCONCEPT22685.EDI" TO cString.
