File Status 48,01


A file opened for I-O gets a 48,01 error when trying to WRITE.


An indexed file is opened for I-O. The application can READ and REWRITE a record, but gets 48,01 when trying to WRITE a new record. 48,01 means that a file that is defined to be access mode sequential is open for I-O, or the file is open for INPUT only.


The problem is in the File Control paragraph FILE-CONTROL ACCESS MODE. In AcuBench, it defaults to “none”, which means sequential. The error message indicates that the runtime is trying to write to a file opened I-O, access sequential, which is not legal. Set ACCESS MODE to DYNAMIC and the problem is resolved.
