Returns the CM procedure name and offset corresponding to a CM logical code
address.
Syntax
cmproc (cmlogaddr)
The string returned by CMPROC can be either of the two following
formats:
Detailed descriptions of each of the above return strings follow:
- entrypoint_name
The name of the CM entry point (primary/secondary).
- procedure_name
The name of the CM procedure.
- base
The output radix used to represent offset, which
depends on the current output base.
% Octal
$ Hexadecimal
# Decimal
- offset
If the offset is nonzero, then it is returned, appended to the
procedure name. The offset is formatted based on the current fill,
justification, and output base values.
Formal Declaration
cmproc:str (cmlogaddr:lcptr)
Parameters
- cmlogaddr
The CM logical code address for which the CM symbolic procedure
name/offset is to be returned.
Cmlogaddr must be a full CM logical code address
(LCPTR). For example:
- CMPC
Current CM program counter
- CMPW+4
Top of CM program window + 4
- PROG(2.102)
Program file logical seg 2 offset 102
- fopen+102
CM procedure fopen + %102 (assumes CM mode)
- cmaddr('fopen')+%102
CM procedure fopen + %102 (NM or CM mode)
Examples
Assume that the following single-segment CM program has been compiled, linked
with the PMAP and FPMAP options, and is now being executed:
PROGRAM test (input,output);
PROCEDURE one;
begin {one}
writeln('ONE');
end; {one}
PROCEDURE two;
PROCEDURE three;
begin {three}
writeln('THREE');
end; {three}
begin {two}
writeln('TWO');
three;
end; {two}
begin {main body} { Outer block is named "ob'" by the compiler }
one;
two;
end. {main body}

The primary entry point ?FOPEN, and the secondary entry point
?MUSTOPEN are located, along with two other offsets within system SL
procedure FOPEN.
Limitations, Restrictions
The names and addresses of nested CM procedures, such as procedure
three, are not available within the CM FPMAP records.
Addresses which fall within nested procedures (three) are returned as
offsets relative to the parent procedure (two).
