I fixed up the file of this morning's message (but still have a listing
in case you want to see it) but it still "DRYROTS". The file is
TRY.SAI[G,MJC]. Is there something special I should know about for-stmts?

A program which I wrote to try to learn a few things (namely SAIL and the
Quam display routines) uncovered a "DRYROT" error. The program is
TRY.SAI[G,MJC], and the error occurred in line 2600. Any suggestions?
JAM again. Sorry, it doesn't go away with
an "IF TRUE THEN", only with an "IF FOO THEN"

JAM here bringing to you yet another
insidious SAIL bug. There is a program
BUG.SAI[MA,JAM] which compiles the following
code incorrectly (see page 6 of source file):
REAL ARRAY Y[1:LN+GWIDTH];
*** LOTS OF STUFF ***
INTEGER ARRAY BUF[1:5500];
*** MORE STUFF ***
The following code appears:
DPGT&DPGT.-6/ PUSHJ P,BEXIT
DPGT&DPGT.-5/ PUSH P,3 ; LOWER ARRAY BOUND???
DPGT&DPGT.-4/ PUSH P,[=5500] ; THIS IS OK
DPGT&DPGT.-3/ PUSH P,3 ; IT SEEMS TO THINK AC3 CONTAINS A 1
DPGT&DPGT.-2/ PUSHJ P,ARRMAK
This, of course, gets a "UPPER BOUND<LOWER BOUND" error
message, for constant bounds yet! Anyway, the problem
goes away if you put an "IF TRUE THEN" in front of
the BEGIN "DPGT". Is that enough?

CASE n OF (ITV, ITV, ... ITV) generates, in at least one case
DONE: POP P,TBITS2
MOVE A,0 ;!!!!!!!!!!!
This is fairly recent (MOVE s/b MOVE A,TBITS2 or whatever).

I RAN INTO PROBLEMS WHEN USING THE SAIL DPB COMMAND.
THE CODE GENERATED FOR THE INSTRUCTION
SEEMED TO LOAD A INTO REGESTER 10 AND PROMPTLY DEPOSIT REG 11.
THE PROGRAM IS TEST.SAI ON [1,EMC], AND THE OFFENDING LINE IS IN THE
AIVCT1 PROCEDURE FOUND ON PAGE 4, I BELIEVE.
