$WW,1$* You run a risk of problems if you do file operations on the same files simultaneously because there is $BK,1$no file sharing/locking mechanism$BK,0$. Generally, the last write wins.
* When using $FG,2$FAT32$FG$, TempleOS does not generate unique short-entry names, the ones with the $FG,2$~$FG$s. Not all $FG,2$FAT32$FG$ filenames are valid TempleOS names and it will complain. Do not access $FG,2$FAT32$FG$ drives not dedicated to TempleOS. Disable them with $LK,"DrvEnable",A="MN:DrvEnable"$(OFF), or they will generate error messages. $FG,2$FAT32$FG$ involves a long and short name for each file.
* The stk does not grow because virtual mem is not used. I recommend allocating large local vars from the heap. You can change $LK,"MEM_DFT_STK",A="MN:MEM_DFT_STK"$ and recompile $FG,2$Kernel$FG$ or request more when doing a $LK,"Spawn",A="MN:Spawn"$().
* The syntax highlighting occassionally glitches. The compiler doesn't.
* Call $LK,"DskChg",A="MN:DskChg"$() when you insert a new removable media.
* Accessing CD/DVD's is flacky. Try $LK,"Drv",A="MN:Drv"$() or $LK,"DskChg",A="MN:DskChg"$() twice.
* You can only $FG,2$extern$FG$ something once. There is a varient called $FG,2$_extern$FG$ which binds a HolyC definition to a asm sym. This, too, can only be done once.
* A terminal task has a $LK,"CDoc",A="MN:CDoc"$ document structure that remains active even when you change $FG,4$Fs->draw_it$FG$. To prevent links in the $LK,"CDoc",A="MN:CDoc"$ from being activated when the user clicks in the window, do one of three things:
$ID,2$
A) $LK,"DocBottom",A="MN:DocBottom"$() followed by $LK,"DocClear",A="MN:DocClear"$() to clear the $LK,"CDoc",A="MN:CDoc"$ so it has no active widgets.
B) Disable window mgr bttn click checking with $FG,4$Fs->win_inhibit$FG$ set to mask $LK,"WIF_SELF_MS_L",A="MN:WIF_SELF_MS_L"$|$LK,"WIF_FOCUS_TASK_MS_L_D",A="MN:WIF_FOCUS_TASK_MS_L_D"$|$LK,"WIF_SELF_MS_R",A="MN:WIF_SELF_MS_R"$|$LK,"WIF_FOCUS_TASK_MS_R_D",A="MN:WIF_FOCUS_TASK_MS_R_D"$. This inhibits window mgr operations but still generates messages from bttn clicks.

* $FG,2$switch/case$FG$ stmts alloc a single jump table--do not use with wide, sparse ranges of case values.
* Don't do a $FG,2$goto$FG$ out of a $FG,2$try{}$FG$.
* A $FG,2$goto$FG$ label name must not match a global scope object's name. (It's not worth slowing-down the compiler to handle this case.)
* $LK,"MemCpy",A="MN:MemCpy"$() only goes fwd.
* A $LK,"Cd",A="MN:Cd"$() cmd must be followed by two semicolons if a $FG,2$#include$FG$ is after it. This is because the preprocessor processes the next token ahead.
* The assembler's error msgs are often off by a line and undefines are cryptic.
* The last semicolon on the cmd line is converted to a dbl semicolon because the compiler looks ahead before doing a cmd. This normally has no negative effect, but when entering $FG,2$if$FG$ stmts with $FG,2$else$FG$ clauses it presents problems.
* You can do a $FG,2$class$FG$ fwd reference by using $FG,2$extern$FG$ on the first declaration, but you can only do ptr references to the $FG,2$class$FG$.
* When doing something like
$FG,2$$ID,2$$ID,2$U0 Main()
{
U16 *_w=0xA0000;
*_w|=0x8000;
}
$ID,-2$$FG$The $FG,2$|=$FG$ will be coded as a $FG,2$U32 Bts$FG$ inst resulting in a $FG,2$U32$FG$ access instead of a $FG,2$U16$FG$ access. This affects some hardware operations.
$ID,-2$
* Compiler warning or error message line numbers will be off if you have a block of word-wrapped comments. You might press $FG,2$<CTRL-t>$FG$ before doing an editor goto-line-number command.
