Changed Behavior Summary
1. #pragma rtGlobals=3 is now the default for new procedure files
As of IGOR Pro 6.30, rtGlobals=3 is the default for new procedure files. This includes the built-in procedure window of a new experiment. Previously the default was rtGlobals=1.
rtGlobals=3 will catch more user programming errors, both compile time and run time, but may require more work on the part of an Igor programmer. This change should not affect the causal non-programmer user of Igor.
This change does not affect existing procedure files or experiments, nor does it apply to code within Macros or Procs.
2. Wave assignment statement change
As of Igor Pro 6.30, with #pragma rtGlobals=3 in effect, code of the form:
wave[index] = expression_using_p_or_x
in a user-defined function generates a compile error if index is a variable.
This change was made because this type of code did not behave as expected.
For example, this now generates a compile error:
Variable index = 33
Variable index = 33
With #pragma rtGlobals=1 in effect such code generates a warning printed in the history area rather than an error.
To fix the error, remove p (and q, r, s, x, y, z, and t as well) from the right hand side expression:
