PROCEDURE TRACE_TRAP_TEST (R6);
"*********************************************************************
" TEST TRACETRAP
" Description:
" If the parameter LEVEL is zero, a tracetrap is generated.
" This is indicated by the variable NOO_INTERRUPT: 0=tracetrap.
"
" The cause-codes (which are only valid after a tracetrap)
" are saved in the array RESULTS[....] :
" RESULTS[0] : register 0,
" RESULTS[1] : register 1,
" RESULTS[7] : register 7,
"
" NOO_INTERRUPT is saved in RESULTS[3].
" #FFFF is saved in RESULTS[4].
" The context_record generated by the tracetrap is saved in
" RESULTS[5] to RESULTS[#14].
"
" The context_record, the cause-codes and the expected cause code
" 2 is printed on the oc, if the variable LOC_OUT_ENABLE is =1.
