I've been having fun going through Guy Cousineau's "Exploring SmartBASIC" document and in the High Resolution Graphics section it says:
The POKE for disabling the value check works as expected. With it in place I am able to supply values above 15 to HCOLOR. However the second POKE for disabling the translation check doesn't seem to work. Once I POKE it, none of the colours work at all. No matter what colour I specify, all my HPLOTs are rendered as black (or maybe transparent). I've also tried POKE 18747 with other values and had no success.In HGR it is highly recommended to disable the check and translation; see HPLOT for applications. The value check is disabled with a POKE of 255 at 11127 (2B76). The translation check is disabled by POKE 18747, 201.
Can anyone provide some insight into what's happening or what I should do differently? I am using SmartBASIC 1.0.
