Assembler from Extended Basic issue

[Assembler from Extended Basic issue]

Thanks everyone for all of the feedback!!  I'll look at it again this weekend to see if I can make any progress.  I know when I compiled my own code, I only used the R parameter, but I'll re-do it just to be sure.  I'll post an update with any progress.

[Assembler from Extended Basic issue]

I've been working through the book "Introduction to Assembly Language for the TI Home Computer" by Ralph Molesworth. Towards the end is a chapter on calling your assembled code from Basic and Extended Basic.

In that example is this code:

 

60 CALL INIT

70 CALL LOAD("DSK1.BSCSUP")

 

Whenever I run this code, I get this error:

 

UNRECOGNIZED CHARACTER IN 70

 

It's the same behavior whether I run this in the Classic99 emulator, or on a real TI/PEB/Editor-Assembler disk in drive 1.  For what it's worth, I get the exact same error when trying to do a CALL LOAD on the code I've assembled myself (that I typed in from the book).

 

Does anyone know what causes this, or possibly have some example code showing how to pass parameters from Extended Basic to Assembly?

 

Thank you.
