Return codes

Your exit routines can affect JES2 processing by directly manipulating JES2 data areas and by passing back return codes. You can have up to 256 individual exit routines associated with a single exit on the EXIT(nnn) initialization statement. These multiple exit routines are all called consecutively in the order of their appearance on the EXIT(nnn) initialization statement. Consider the following example:

    EXIT(175) ROUTINE=(X1,X2,X3,X4,X5,...)

For Exit 175, the exit routine identified by label X1 is called before the exit routine identified by X2, and so forth, until all of them (X1 through X5) are called or until one of them generates a nonzero return code, which causes the exit effector to return to the JES2 mainline after the exit point.
