Comment Lines interfere with continuation lines

Maybe it's an LC version issue. I'm using 5.5 and there was no compile
error flagged on the original code I published, nor on my test that simply
had the line "with p1,p2" in the script.

It seems you can use some reserved words as command/function names. I tried
code in the format "put xxx(p1,p2) into t"  with various reserved words as
"xxx" and many of them compiled with no errors, including "with", "if",
"card", "stack", "filename","put" but using "ID" or "into", or
"itemdelimiter" caused a compile error.

I was able to create a function named "filename" with no compile errors but
a function named "put" wouldn't compile.

I would never use a reserved word as a command or function name in real
life but maybe those wiser than me can explain the differentiation between
types of reserved words.
