13 Nov. 2018 - Cleaning up code, removing (at least temporarily) routines that aren't vital, or useful. - Fire graphics code. **Probably temporary. - Factoring code. **Probably permanent. - Optimized CopyHex - ConvHexStr is reorganized to be smaller14 Nov. 2018 - Optimized ConvOP1 to be smaller, updated performance analysis - Optimized GetPixelLoc 3 bytes smaller, 10cc faster - Optimized ReadArc routine. 3 bytes smaller, 18cc faster for archived data, 3cc slower for data in RAM. - Removed LoadTSA as the only internal usage was to load the ReadArc routine. Instead it is a specialized routine that no longer destroys IX. Next savings of 11 bytes, even after extended the mov9 LDI chain to a mov13. Saves 172cc overall (186cc, actually, since no more ld ix,**) - Error also takes advantage of mov13, saving 2 bytes. - Added a few more fixed-size moves, including mov768. Total cost was 6 bytes. - ClrHome uses the faster SetSmallMem, saves a byte. Makes it 901cc faster, roughly 21% faster - I removed the unknown routine I labeled "lbl000", as it isn't used anywhere (or shouldn't be!) It looks like an attempt at making an off-page call, probably when the low mem scared me. - Optimized and fixed IsHexTok. It used to accept the ' and ' token as equivalent to 9. Saved a byte and 2cc when the token was 0~9. - Optimized DE_Times_BC. No change in size, 120cc faster in the average case. No longer leaves A=0. - optimized HL_Div_BC to be 264cc faster on average, with a net cost of five bytes. DE_Div_BC is now the subroutine, though, and is 272cc faster than if you had called it previously. Nearly 18% speed up - Fixed SearchString at a cost of 8 bytes, but should perform roughly 4 times faster. Also, there is now no risk of it entering an infinite loop, an issue the previous routine had. - SqrtHL is optimized. Actually replaced with SqrtDE. Saved 2 bytes, on average 261cc faster (20.17% faster). Worst case is still 165cc faster (12.75% faster).15 Nov. 2018 - I replaced the Sqrt routine with Runer112's from Axe. It is 221cc faster with the small modifications on my part to fit the output registers, and 2 bytes smaller. That's roughly 21.5% faster. - Removed ConvNumBase and HL_Div_C. HL_Div_C was only used by ConvNumBase, and ConvNumBase wasn't used anywhere in the code. - Changed Is_2_Byte. It's no faster or slower, just a little more sensible and readable. - Removed HexTok and GetHexAtDE. - Moved CompatCall so it didn't have to JP to IsOP1GrammerProg, saving 3 bytes and 10cc - Removed EndHook2 as it appears unused? - Optimized ONErr to be 1 byte less, 2cc faster. - Optimized TileMap1. 21cc faster, 2 bytes smaller. - Removed HL_SDiv_BC replacing the only use of it with a wrapper around a call to HL_Div_BC. Net 21 bytes smaller. Signed division command now averages about 47cc faster. - Removed PutIM, ParseFullArgI, CallI, CopyZStr, CreateZVar, FindVar. - Renamed memory addresses in the Menu command. May have messed something up. - vPutscr is 1 byte smaller, 3cc faster. - Optimized DrawRectToGraphI since it didn't need to preserve registers. Saved 9 bytes.19 Nov. 2011 - Did some testing and fixed some new bugs. - Fixed LoadReadArc. Needed 6 more bytes, saves another 76cc. - Opted to use interrupts for the Pause routine. It isn't as close to 1/100 seconds, but it is more energy efficient, smaller, and more reliable.
