8.2.10 Read and Convert a Hexadecimal Number scanx
Syntax
scanx(&lvariable)
&lvariable: Address of an .L variable (e.g. %V100.L) where the ASCII -> signed integer
conversion of the string entered from the keyboard will be loaded.
Reads and converts a hexadecimal value entered from the keyboard. This function must be called after a scano() or
scanu() dialogue opening function.
The conversion stops on the first non-hexadecimal character. If no hexadecimal characters are detected, %lvariable
is loaded with 0.
Operation
This function is used to receive the value of a hexadecimal number at the end of an operator dialogue.
If the dialogue is still in progress (line feed key not pressed), the code 0 is returned. It is therefore necessary to call
scanx() cyclically until the end of the dialogue.
Return code
If OK
0: Dialogue in progress.
1: Number successfully read and converted. The result is transferred into
variable .L pointed to by &lvariable (the dialogue is finished).
The conversion stops on the first non-hexadecimal character.
