Hi, long time: If the value of the expression higher than the quantities of the line numbers after GOSUB, a SYNTAX ERROR occurs: 10 A = 3 20 ON A GOSUB 30, 40: END 30 PRINT "1": RETURN 40 PRINT "2": RETURN

Edited: Okay, SCREEN 5,,0,0,0 Should be the first page. and is the only page that holds a BLOAD image, SCREEN 5,,1,1,0 is the second page that displays an image.done by commands but doesn't hold an image by BLOAD. SCREEN 5,,2,2,0 is a third page, and as same as page 2, definitely is not holding any image after a BLOAD. This should be considered a bug. Ronald.

Okay, SCREEN 5,,0,0,0 Should be the first page. Yet doesn't display a previews image, SCREEN 5,,1,1,0 is a second page which displays the loaded image. SCREEN 5,,2,2,0 is a third page, which I'm not sure if it's loading or retaining the image, but page 0 definitely is not holding any image. This should be considered a bug. Ronald.

Yes, the WAIT statement is like a port and WAIT &H3DA, 8 is to stop flickering. That I understand, but still the SCREEN 5,,1,1,0 statement for page 1 and SCREEN 5,,2,2,0 for page 2 looks like it's not working. I could displayed the images, but I don't know why the pages function is not working proerly. Can you veryfy if SCREEN 5,,2,2,0 is a diffrent page than page1? Thanks, Ronald.

Hi there!!! "Mr. chjmartin2" from VCF forum made a program for GWBASIC on TANDY (that works fairly on DOSBOX) can view images of 24-bits splitting screen pages that simulates 85 colors in a simple, but a very clever program, which I will like to see if PC-BASIC can handle. I tried but, it didn't work. I got a blank screen, thou it froze. Here's the article site:http://nerdlypleasures.blogspot.com/2016/01/milestones-in-ibm-pc-compatible.html in the topic: 2012 - Tandy 85-Color Picture Viewer. In the...

Sorry, is not PEEK(13) is 14... hexadecimal: &HE. Ron.

Hi! Can it be possible to set into the PCjr section an identification byte in a memory located F000:FFFE or after the statement "DEF SEG = &HFFFF" completed, a display of hexadecimal 'FD' (byte #253) with peek(13) (&HE)? Some programs use a PEEK into machine memory, specificly at this address to identify the type of machine as a PCjr or IBM PC or wiselike. See: http://stanislavs.org/helppc/id_bytes.html I know that it could be an issue because PC-BASIC is an emulator and it, actually, have not physical...
