How to read crossref file

[Jason Martin]

Was there or is there a guide to reading the crossref file.

I went all the way back to 1998 in the stuff I have and could not find anything.

Not necessarily just for me.

Not that I know of. I always considered it as a given from the PL/I and COBOL days. Not to spark a discussion, but I never use them, because I prefer my variable references to be very short-lived, by localizing them to stack based ones. The few remaining globals I can remember most of the time.

I will have a look.

best regards,

René.

The one you get when you compile a NetRexx program with -crossref option

What do the letter codes mean a, v, p?

Why do some lines start #= and others just letter code and line #'s

--- Variables for class NetRexxS ---

args      String[]       a 98 101 102 102 102

compiler  NetRexxC       p 23 89

ex        IOException    v 60= 61

filecount int            p 30 36= 45= 87 87=

i         int            v 82= 83 83 84

items     Rexx           v 80= 81 82 88

lapsed    long           p 28 35= 44=

line      Rexx           v 70= 71 80 83 87

port      Rexx           a 54 56 57

port_     Rexx           a 41 42

rd        BufferedReader p 24 68= 70

retCode   int            v 89= 90

sock      Socket         p 22 67= 68 69

srv       ServerSocket   p 21 56= 67

startTime long           p 26 34= 43=

strAr     String[]       v 81= 83= 84 88= 89

wr        PrintWriter    p 25 69= 89 90 91 92

From memory:  Argument, local Variable, Property

 

 Why do some lines start #= and others just letter code and line #'s

 

Again from memory, the '=' indicates that the value of the variable is changed on that line (as opposed to just being used).

Thanks, I mostly ask so a new user can read the file.

I see letter codes none,a,c,p,v.

I will look at the source to figure out what they mean.

Thanks again about the = sign.

Could be 'none' is local/automatic variable.  'c' might be 'constant'? 
This was never part of language so wouldn't be in the book, but I'd have thought I would have documented it somewhere :-(.  Apologies.

OK!  A summary would be good when you have decoded it .. I remember a lot of effort went into making that work correctly.

 

Thanks again about the = sign. 

 

:-)  I remember that being especially useful on occasion, when some variable was referred-to dozens of times but only got changed in three places -- one of which one had forgotten, but of course that case was always the culprit for some weird behaviour ...

From the source I see:

a -- argument

c -- a constant

p -- a property

s -- a static

v -- local variable

= -- value of variable changed
