decimal-point is comma is no longer handled

That worked until we switched away of cob_get/put_field_str, can you handle the decimal point depending on module->decimal_point, please?

Current handling of decimal-point is comma:

(gdb) cp /d SOME-VAL
Name:        03 SOME-VAL/SOME-REC/PROG1 [W-S]
Display:     +000000000000.000000
Hex:         0x30303030303030303030303030303030...(18 total bytes)
Field:       <none>
Base:        b_352    ( 0x7fffe784a720 )
Offset:      39
Length:      18
DataLoc:     0x7fffe784a747
Attr:        a_24
AttrType:    16 (0x10) NUMERIC_DISPLAY
AttrDigits:  18
AttrScale:   6
AttrFlags:   0x1 HAVE_SIGN
Data: (HEX)   [ 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 ]
Data: (ASCII) "000000000000000000"

the display is expected to be

+000000000000.000000

more important

(gdb) cp SOME-VAL=15,34
No symbol matches "15,34" in current context

is expected to work.

TODO: check module->decimal_point and use this (that is in since old OpenCOBOL days and works) instead of the fixed .
