| Description |
converts any ASCII character to its corresponding numeric equivalent in the range 0 to 255.
This "seq" function is the opposite of the "char" function. Any expression can be used as an argument, but all characters are ignored beyond position 1. The "seq" of a null string ends up using the segment mark (x'ff') end-of-string delimiter as the argument resulting in a value of 255. |
