|
|
* $SYNTAX$
|
|
* FT_HEX2DEC( <cHexNum> ) -> nDecNum
|
|
* $ARGUMENTS$
|
|
* <cHexNum> is a character string representing a hex number.
|
|
* $RETURNS$
|
|
* A decimal number.
|
|
* $DESCRIPTION$
|
|
* Converts a hexadecimal number to a BASE 10 decimal number.
|
|
* Useful for using FT_INT86().
|
|
* $EXAMPLES$
|
|
* FT_INT86( HEX2DEC( "21" ), aRegs )
|
|
*
|
|
* Converts 21h, the Dos Interrupt, to its decimal equivalent,
|
|
* 33, for use by FT_INT86().
