CodeWatch

The sample demo sessions in the back of the CodeWatch User's Guide may not match exactly with this version of CodeWatch.
CodeWatch is unable to evaluate an array in a based structure when the dimensions of the array are declared using the REFER option.
Problems may arise when evaluating expressions containing certain built-in functions, especially when given incorrect arguments (for example, wrong type or wrong number of).
EVALUATE of BASED and CONTROLLED arrays do not work when using CodeWatch with Open PL/I.
When using CodeWatch with Open PL/I, EVALUATE can not use the POSITION attribute.
On platforms where the WIDECHAR data type is supported, Codewatch allows evaluation of WIDECHAR variables only. Evaluation of WIDECHAR expressions is currently not supported.
For WIDECHAR variable evaluation, half byte-pairs outside the ASCII range display as a '.' character. Use the EVALUATE command with the /h option to display hexadecimal values for each byte-pair. For example:
```
dcl wc wchar (16) init('003900370038'Wx);

...

eval wc

WC = .9.7.8. . . . . . . . . . . . .  {widechar (16)}

eval /h wc

WC = 00 39 00 37 00 38 00 20 00 20 00 20 00 20 00 20 00 20 00 20 00 20 00 20 00 20 00 20 00 20 00 20 (hex)  {widechar (16)}
```
