Perlmind Programming Journal (PMPJ)
Updating the Ghost Perl AI in conformance with MindForth AI.

Today we return to Perl AI coding after updating the MindForth code in July and August of 2016. In Forth we re-organized the calling of the subordinate mind-modules beneath the MainLoop module so as no longer to call the Think module directly, but rather to call the FreeWill module first so that eventually the FreeWill or Volition module will call Emotion and Think and Motorium.

We have discovered, however, that the MindForth code properly handles input which encounters a bug in the Perl code, so we must first debug the Perl code. When we enter, "you see dogs", MindForth properly answers "I SEE NOTHING", which is the default output for anything involving VisRecog since we have no robot camera eye attached to the Mind program. The old Perl Mind, however, incorrectly recognizes the input of "DOGS" as if it were a form of the #830 "DO" verb, and so we must correct the Perl code by making it as good as the Forth code. So we take the 335,790 bytes of ghost175.pl from from 2016-08-07 and we rename it as ghost176.pl for fresh coding.

We start debugging the Perl AudRecog module by inserting a diagnostic message to reveal the "$audpsi" value at the end of AudRecog. We learn that "DOGS" is misrecognized as "DO" when the input length reaches two characters. We know that MindForth does not misrecognize "DOGS", so we must determine where the Perl AudRecog algorithm diverges from the Forth algorithm. We are fortunate to be coding the AI in both Forth and Perl, so that in Perl we may implement what already works in Forth.

In Perl we try commenting out some AudRecog code that checks for a $monopsi. The AI still misrecognizes "DOGS" as the verb "DO". Next we try commenting out some Perl code that declares a $psibase when incoming word-length is only two. The AI still misrecognizes. Next we try commenting out a declaration of $subpsi. We still get misrecognition. We try commenting out another $psibase. Still misrecognition. We even try commenting out a major $audrec declaration, and we still get misrecognition. When we try commenting out a $prc declaration, AudRecog stops recognizing the verb "SEE". Then from MindForth we bring in a provisional $audrec, but the verb "SEE" is not being recognized.

Although in the MS-DOS CLI prompt we can evidently not run MindForth and the Perlmind simultanously, today we learn that we can run MindForth and leave the Win32Forth window open, then go back to running the Perl AI. Thus we can compare the diagnostic messages in both Forth and Perl so as to further debug the Perl AI. We notice that the Forth AudMem module sends a diagnostic message even for the blank space ASCII 32 even after "SEE", which the Perl AI does not do.
