System Builtin Name MI Instruction name Prototype Name Description Usage Examples

_QTEMPPTR ~ qtempptr Return a system pointer to current process' QTEMP. t050.rpgle. Test of _QTEMPPTR.

__setjmp ~ setjmp Store the current invocation and statement into an invocation pointer and a label pointer respectively. t063.rpgle. Test of __setjmp and libc routine longjmp().

__setjmp2 ~ setjmp2 Store the current statement into a label pointer. t062.rpgle. Test of __setjmp2. This example program also introduces a useful 'Where am I?' technique.
