[Info-vax] Debugging a Pascal program under VMS V9.2-2

[Single Stage to Orbit]

OK this is strange and maybe I've misundersood something but basically
I can't exmaine values of variables, as below. 

─ SRC: module START_RECEIVER -scroll-
source─────────────────────────────────────────────────────────────────
────────────────────────
    39: End;
    40:
    41: (* Declaration of lib$get_symbol *)
    42: Procedure lib$get_symbol ( %DESCR symbol : Varying [$l1] of
char;
    43:                            %DESCR value  : Varying [$l2] of
char); external;
    44:
    45:
    46: Var
    47:   username : Varying [15] of char;
    48:   output_dev : Varying [16] of char;
    49:
    50: Begin
->  51:   translate_logical('NWAY$PATH',pathname);
    52:   translate_logical('SYS$OUTPUT',output_dev);
    53:   translate_logical('STARTREC$USERNAME',username);
    54:   username := username + '_NetV2';
    55:   status := $CREPRC( image := pathname + 'REC.EXE',
    56:            output := output_dev,
    57:            baspri := 3,
    58:            prcnam := username );
    59: End.
─ OUT -

──────────────────────────────────────────────────────
stepped to START_RECEIVER\START_RECEIVER\%LINE 51
    51:   translate_logical('NWAY$PATH',pathname);











─ PROMPT -error-program-

Versions in use -

OpenVMS x86 V9.2-2
DEBUG V9.2-009
PASCAL: V6.3-143 (GEM 50XC4)

I have checked and I have definitely compiled the program with /DEBUG
/NOOPTIMIZE, and linked using /DEBGU

Any ideas?
