The character is a numeric digit, from 0 to 9. All but the first of these digits corresponds to a specific size window, but the 0 character is the first byte of a nine byte field. The other bytes define the size of the window by listing the edges as two-byte integers, in this format:..."

I get rects and V1,H1,V2,H2 coordinates But not how to specify them in a string.

My question: If I enter a 0 as the first character of the alert string how do I then enter the four two-byte integers in the nine byte field? I've tried several things and I'm thinking it's simple but I'm not getting it. I know there are calls I can make providing templates but I'm trying to get this resource example working specifying a custom alert size.

resource rAlertString (1) {
"43/"
"Frame 1.0\n"
"by Mike Westerfield\n"
"\n"
"Contains libraries from ORCA C,\n"

"/^#0\$00";
};

The rectangle needs to be broken up into 8 bytes (keeping in mind the
words are little endian). Assuming a rectangle of (20, 20, 180, 620),
convert it to hexadecimal (0x0014, 0x0014, 0x00b4, 0x026c), convert it
to bytes (0x14, 0x00, 0x14, 0x00, 0xb4, 0x00, 0x6c, 0x02), and embed it
("0\0x14\0x00\0x14\0x00\0xb4\0x00\0x6c\0x02" ... )

Thank you much.
I belatedly found what should have been enough to clue me in in chapter 10 of the ORCA/C manual but I still would have had trouble with it without your help.

Another option would be to replace the rAlertString rez definition:

(don't update types.rez, just put this in your rez file before using it.
There will be a warning about the redefinition but compile rez=(-rd) will
disable it).

type rAlertString {

switch {
case sizeCustom:
key byte = 0x30;
rect;
case size30: key byte = 0x31;
case size60: key byte = 0x32;
case size110: key byte = 0x33;
case size175: key byte = 0x34;
case size110: key byte = 0x35;
case siz140: key byte = 0x36;
case size200: key byte = 0x37;
case size250: key byte = 0x38;
case size300: key byte = 0x39;
};

switch {
case iconNone: key byte = 0x30;
case iconCustom:
key byte = 0x31;
longint;
int;
int;
case iconStop: key byte = 0x32;
case iconNote: key byte = 0x33;
case iconCaution: key byte = 0x34;
case iconDisk: key byte = 0x35;
case iconDiskSwap: key byte = 0x36;
};

string;
string = $"00";
};

Example usage:

resource rAlertString (3) {

sizeCustom { { 12, 34, 56, 78 }},
iconNone {} ,
"/abc/#0"
};

resource rAlertString (4) {
size30 {},
iconCustom { 12, 20, 40 } ,
"/abc/#0"
};

Note the empty {} are required even if it's a standard size or icon. The
trailing $00 terminator is automatically provided.
