Working with XB28GEM20210815, renamed and loaded onto SD card for Finalgrom99. TI console, P-box, 32k. Typed in program from page 14, post #327, by senior falcon, to demonstrate XB256, T40, T80, and TML. Syntax error in line 31, where FOR, CALL LINK("PRINT"), and NEXT are on one multi-statement line. Retyped program to put them all on separate lines. Runs. If the program crashes from syntax error, if I try to EDIT any lines, XB256 refuses to let me, get garbled statements, etc.
