The Question is: Hi, When running a Basic program with debugger on VAX setting a break point at the error handler the show calls command gives the line number at which the error occured. How can we get the same information when running a program on AXP? For example: 1 on error go to 5 2 input A 3 print a/0. 4 go to 10 5 print ert$(err) 6 resume 10 10 end We set the break point to line 5. When running on AXP issuing SHOW CALLS gave: *Y$MAIN Y$MAIN 5 rel PC abs PC When running on VAX issuing SHOW CALLS gave: *Y$MAIN Y$MAIN 5 rel PC abs PC SHARE$BASRTL SHARE$BASRTL ----above condition... %systrm-f-fltdiv_f... ----end of exception... *Y$MAIN Y$MAIN 3 rel PC abs PC (This is the information we need on the AXP) Thank you, Haim Pri-Tal The Answer is :
The OpenVMS Wizard would initially assume the desired behaviour would
result from the use of /DEBUG/NOOPTIMIZE or similar compilation options.
$ cre x.bas
1 on error go to 5
2 input A
3 print a/0.
4 go to 10
5 print ert$(err)
6 resume 10
10 end
Exit
$ bas/noopt/deb x
$ lin/deb x
$ r x
