Indicating whether large files are permitted
Access to large files can be controlled with the ADD-FILE-LINK command and the operand EXCEED-32GB, without intervention in the program.
/ADD-FILE-LINK SUPPORT=*DISK(EXCEED-32GB=*BY-PROGRAM/*FORBIDDEN/*ALLOWED,...)
The EXCEED-32GB operand defines whether the processing of large files is allowed (*ALLOWED) or not (*FORBIDDEN).
The specifications in the TU FCB are used for the default setting *BY-PROGRAM. This operand is entered in the TFT (Task File Table) and is evaluated when the file is opened.
Outputting file attributes
In the S variable output of the SHOW-FILE-LINK command, the validity of large files as specified in the TFT is output in the S variable var(*LIST).EXC-32GB (declared using the ADD-FILE-LINK command or the FILE macro).
Contents of the S variables: ’’ (corresponds to BY-PROGRAM) or *FORBID or *ALLOW.
