Configuring and Writing REXX › Understanding the Global Variable Environment

Understanding the Global Variable Environment

The global variable environment allows your REXX programs to access and modify the values of all variables in the GLV variable pool. The GLV variable pool contains:

• CA Automation Point status variables:
  • Volatile (normal status variables)
  • Nonvolatile (disk based—stored in the AXC.glv file)

  For more information about CA Automation Point status variables, see the chapter "Writing Rules."

• Other GLV variables:
  • Volatile
  • Nonvolatile (disk based—stored in .glv files)

REXX programs use GLV variables by placing their values into local REXX variables having the same names for processing. You can update GLV variables by assigning them the value of the local REXX variable, or you can update them directly.
