Re: parse a negative number out of a before image string

so after this executes...

%subst(char_area
:%size(packed_data)-field_bytlen+1 // = 9-5 + 1 = 5
:field_bytlen) // = 5
= %subst(trigger_buf:field_pos:field_bytlen);

i have this...

EVAL ds_chararea
DS_CHARAREA.PACKED = 40404040000000000 4040404040404.
DS_CHARAREA.ZONED = .


i'm processing a decimal(9,2)...

then data decimal error.

found it dave... i'm having trouble with this...

d char_area ds 260
d varchar2_data 256a overlay(char_area:1) varying(2)
d varchar4_data 256a overlay(char_area:1) varying(4)
d zoned_data 31s 0 overlay(char_area:1)
d packed_data 31p 0 overlay(char_area:1)

when field_type = 'P';
packed_data = zero;
%subst(char_area:%size(packed_data)-field_bytlen+1:field_bytlen)
= %subst(trigger_buf:field_pos:field_bytlen);
dsply packed_data; // adjust decimal position if needed

when assigning the string to the char_area....

:%size(packed_data)-field_bytlen+1:field_bytlen)

for my decimal(9,2) subject, it would build char_area starting position

to

be...
9 - 5 = 4 + 1 = 5

so why would we assign char_area starting at position 5?

Because numeric data has to be right-justified in the packed data
area -- which is 16 bytes long.
