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>.
