User Symbol Override Table

The user symbol override table user exit, USOT, allows you to define global symbols that override symbol definitions in the local symbol table or the common symbol table. For example, you can define symbol D0 in the symbol override table as a pointer to the storage block on data level 0 to override the definition in data macro (DSECT) CPSEQ, which has a value of 0.

The following search order is used in the symbol lookup process:

  1. The user symbol override table.
  2. The local symbol table or the common symbol table.
  3. The user global symbol table.
  4. The IBM-provided global symbol table. This table is defined in the cgstab.cpp file, which is found in CUDA.DLL.

Input
