Hi, does anyone know a good way to make a popup/alert box scroll so it is possible to add more text to a popup/alert?

Thanx

I don't believe there is way using a built-in PocketC command.

Try the Note function in my PToolbox lib. Use command 0x300 (string-in-string-out mode, edit disabled, underlines disabled).

Joe, I am 'bit' challenged.
Would you please provide a translation of how you took 0X300 (in your Note example above) and got string-in-string-out mode, edit disabled, underlines disabled... I'm looking at your documentation for pToolBox in the Note section... What does bit 2:0 mean? Etc. etc... Thanks...

The "0x" prefix makes it a hex number. The 300 is a 3 digit hex value. Each hex digit is 4 bits in length. In PocketC, a hex number can have up to 8 digits (32 bits total).

In this case, the left most digit is bits 11:8 (11 to 8), the next to bits 7:4 (7 to 4), and the right most to 3:0 (3 to 0).

Hex digits are are as follows:
hex binary
0 0000 (no bits set)
1 0001
2 0010
3 0011
4 0100
5 0101
6 0110
7 0111
8 1000
9 1001
a 1010
b 1011
c 1100
d 1101
e 1110
f 1111 (all bits set)

In the case of 0x300, bits 9 & 8 are set.

Example: 0xc0040003 has bits 31,30,18,1, & 0 set.
