Here's an include file that provides the ability to convert back and forth between integers and hexadecimal numbers.

After INCLUDE'ng this code into your macro:
To convert a hex number to an integer:

Triane,

Great code. 1 Problem though.

Here's what I'm trying to do:

Even worse, set tmp = 0x10


INFINITE LOOP

Here's an update, it works just fine in both scenarios presented.

One important note: The Int2Hex procedure expects the integer to be an unsigned type, up to 40 bits in length. If you pass it a negative, signed integer, it probably will not return valid results (and may indeed break).

If your integers are signed values, you will have to convert them to unsigned before handing them to the routine. I cannot convert them because I have no way of knowing if it's a short integer (8 bit), an integer (16 bit), a long integer (32 bit), a double-long integer (64 bit) or something else entirely (40 bit for example).

To convert a signed integer to an unsigned integer, simply add the unsigned value of the largest bit in the integer type. For example, if you were using a long-integer, (32 bits in length) you would need to add 2^31 (or 2,147,483,648) to the negative value in order to generate an unsigned result.

The macro cannot handle double-longs as written (it maxes out at 40 bits). Nevertheless, you could try extending this simply by adding to the "Powers of 16" list. I didn't do this because I don't know whether or not, ACtool can handle double-long integers. So I stopped at 40-bits.

PS: I do not know if the Hex2Int routine will return signed or unsigned values because that conversion is handled within ACTool's dataset routines and I don't know how Cam wrote it to behave.
