BUGS

At the bottom we have a category for bugs which are fixed. The motivated mathematica/C++ programmer might move bugs down into this category.

Problem : SmallBasis[] in NCProcess[] doesn't keep the UserSelects
One can specify UserSelects which may be removed by SmallBasis[].
Answer : Need new option which keeps the "NewSelects"
Sun Jul 18 18:34:17 PDT 1999: Who does this? -- Mark

Date: 4/4/99
Problem : bug10.m - NCProcess[ 2,0,0,0,$file, SB->True ] does bad things !=
Problem: The output of NCProcess is a**Inv[a] -> 1 which is obviously not equal to the ideal generated by the input.
Answer:
Sun Jul 18 18:34:17 PDT 1999: Not specific? -- Mark

Date: 11/23/98
Problem : Calling NCProcess twice kills
Answer : NCProcess doesn't protect variable "start"
Sun Jul 18 18:34:17 PDT 1999: Think it is fixed? -- Mark

Date: 10/24/98
Problem : bug9.m ---- Running NCProcess[] with UserSelect-> set then running NCProcess[] with no UserSelect marks some relations with \Uparrow even though there are no "User Selects". (Some variable is not properly scoped.)
Answer :
- Sun Jul 18 18:34:17 PDT 1999
- Suggested fix: add some call like ClearUserSelects to the beginning of the NCProcess file

Date: unknown

Problem: bug2.m --- This kills the C++ module. My first attempt at using the small basis option. Didn't set SBByCat->False.

Error message given at time of death:
InputClass::error(70,73)That is: Function
 Integer

***Error in file InputClass.c on line number 51.
By the way, your version of the code was compiled at 17:28:20 on the day Sep  1
1998.
In the function DeselectForSPolynomial.
You are using factory version:0

Setting SBByCat->False and SB->True worked.

Date : Unk

Problem: bug3.m --- This kill the C++ module Options[ NCProcess ] reveals RRByCat-> True as an available option.

The error message at death is :
In the function WhatAreNumbers.
Debug1::s_OUTPUT_CHECKER_NUMBER originally was 1 and now has the value 35 rather
 than zero.
***Error in file MmaSpecific.c on line number 226.

The call occured while in the context :Global`

Out[12]= $Aborted

Sun Jul 18 18:38:27 PDT 1999: Need more information. Which bug file?
Answer bug3.m

Date : Unk
Problem: 6. Why is it not OK to specify DegreeCap w/o DegreeSumCap ???
Sun Jul 18 18:39:32 PDT 1999: Design choice ask bill?

Date : Unk
Problem: bug6.m ---- NCMakeGB[] run from within mma gives a finite GB but FoundBasis[] returns 0.

Date : Unk
Problem: bug7.m ---- NCProcess[] run from within mma with
```
<<  bug7.m 
```
gives a finite GB but FoundBasis[] returns 0.
Answer: Mark Says FoundBasis[] only applies to MakeGB not NCProcess[]

Date: 7/7/99
Problem: bug5.m Underscores not allowed in filenames
Answer:

FIXED

Date: 3/3/99
Problem : NCtermsOfDegree[] needs NCExpand
Answer : Fixed Call NCExpand[]::: NCTaylorCoeff.m now lives in FORNC99

Date: unknown
Problem: bug1.m ---- Short file names don't work
Answer: Mark fixed 7/9/99
