Since getting a new computer with 64-bit Windows, I'm trying to convert an old TP6 program to run as 32-bit. I was able to get it to compile with little issue, but it cannot read the data file.
The program is a little gas mileage and similar program I wrote ages ago. I still use it. It stores the data in binary format as a record, which is set as this:
type
alpha = string[8];
b_type = string[11];
menu_line = string[20];
d_type = string[35];
screen_line = string[80];
path_string = PathStr;
char2 = string[2];
gasrec = record
case info_type: char of
'X': (last_acc : word;
start_mile: longint;
fil_size : longint);
'1': (gas_date : word;
odometer : longint;
gas_used : longint;
price_gal : word;
price_paid: longint;
brand : b_type);
'2': (spcl_date : word;
spcl_odom : longint;
spcl_price: longint;
spcl_descr: d_type;
spcl_wrnty: char)
end;
The problem is that it doesn't seem to read it in properly. Looking at the binary data, it looks like the word and longint sizes may not match. I'm not sure how to force word to 16-bit and longint to 32-bit, as it seems to be reading them in as 32-bit and maybe 64-bit?
This is the piece of code that reads the first entry:
with data_info[0] do
begin
last_accessed:=last_acc;
start_mileage:=start_mile;
file_size:=fil_size
end;
This is what the watch on data_info shows:
data_info = {{INFO_TYPE = 88 'X', LAST_ACC = 947, START_MILE = 0, FIL_SIZE = 0, GAS_DATE = 947, ODOMETER = 0, GAS_USEThis is the view of the file:
