PDR1016S

Invalid <IO> tag location value. <IO> must be MEMORY, HIPERSPACE, DISK, TRANSFER, or OPTIMUM.

What happened: You specified a value other than MEMORY, HIPERSPACE, DISK, TRANSFER, or OPTIMUM for the Input or Banner group <IO> tag. The invalid location value is given.

What to do: Specify:
  • MEMORY if your input file is small and can be stored completely in REGION memory (up to 2 gigabytes of virtual memory).
  • HIPERSPACE if your job is too large for memory, but not over your system maximum Hiperspace size.
  • DISK if your input file is very large and you want to store it in a temporary VSAM disk file.
  • OPTIMUM to let Enrichment switch as it needs more room. For OPTIMUM, Enrichment starts in memory and moves to Hiperspace if memory fills up. If Hiperspace fills up, Enrichment switches to disk.
  • TRANSFER to let Enrichment transfer between Hiperspace and disk, without using memory.
You should probably always use OPTIMUM for your <IO> tag location value, unless you have a very large input file.
