#279 NUL characters not shown in trace output

[Robert AH Prins]

When tracing code that inserts NUL (x2c(00)) characters, the trace output will simply not display them:

Code:

/* REXX */
trace ?i
pull q
q = '='x2c(00)|| q || x2c(00)'='
say q

Output of trace:

3 *-* pull q
>>> "123"
+++ Interactive trace. "Trace Off" to end debug. ENTER to continue.
4 *-* q = '='x2c(00)|| q || x2c(00)'='
>L> "="
>L> "00"
>F> ""
>O> "="
>V> "123"
>O> "="
>L> "00"
>F> ""
>O> "="
>L> "="
>O> "="
5 *-* say q
>V> "="

In tracing output a blank will be shown where a NUL character would appear in the value of a variable to ensure that it appears that a character is present. Fixed for v3.8RC2
