将大约80 KB的巨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).

Answer 1

你真的需要mempointer吗？否则你可以直接将COPY-LOB变成LONGCHAR.

DEFINE VARIABLE cString AS LONGCHAR   NO-UNDO.

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