  • Closed as program error.

Error description

  • Development analysis confirmed that the permitted memory
    allocation size of an application is controlled by the Storage
    Model. When compiling a Cobol program and creating a program
    (CRTCBLMOD and CRTPGM programs respectively), there is an option
    called STGMDL. By default the limit for a single allocation is
    about 16 MB (not 8 MB as the user suspected). This can be in
    principle increased to STGMDL(*TERASPACE) and that would allow
    more than 16 MB in a single allocation.
