HLASM provided insufficent diagnostics to determine a AGO/ANOP loop during an assembly causing many duplicate symbol errors

HLASM used excessive CPU assembling a program. The error happened because we had coded a AGO/ANOP loop. That meant HLASM logged many 'duplicate symbol' errors internally since the AGO/ANOP loop encompassed most of the program. However, since it did not complete pass one, it did not report any of the errors. The default ACTR value would have eventually terminated the assembly, but when the job was cancelled, HLASM had already 'assembled the program' 500 times. Reducing the ACTR count may have helped (resulting in msg ASMA013S ACTR counter exceeded), but with the vast number of AGO/AIF statments in the program, it would have taken a long time to determine the source of the problem

    Given the problem this has caused - and we've seen it many times before - looking had better diagnostics for AGO/AIG/ANOP macro loops is worth investigating. We will add it as an uncommited candidate. Sharuff.
