我有一个问题要讨论。我正在研究INFORMIX 4GL程序。该程序生成输出文本文件。这是输出的一个示例:
Lot No|Purchaser name|Billing|Payment|Deposit|Balance|
J1006|JAUHARI BIN HAMIDI|5285.05|4923.25|0.00|361.80|
J1007|LEE, CHIA-JUI AKA LEE, ANDREW J. R.|5366.15|5313.70|0.00|52.45|
J1008|NAZRIN ANEEZA BINTI NAZARUDDIN|5669.55|5365.30|0.00|304.25|
J1009|YAZID LUTFI BIN AHMAD LUTFI|3180.05|3022.30|0.00|157.75|
从输出文本文件(.txt)文件中,我们可以从excel(.xls)文件中手动打开它。从这种情况来看,是任何4gl代码或任何我们可以用它来打开文本文件的命令在我们运行程序后,在microsoft excell中自动生成?如果有任何想法,请与我分享...谢谢

显示的输出采用正常的Informix UNLOAD格式,使用管道作为字段之间的分隔符。对Excel最近的方法是使用逗号分隔值的CSV文件。从该输出中生成其中一个有点繁琐。您需要将包含逗号的字段括在双引号内。您需要使用逗号代替管道。你也可能不得不担心反斜杠。
在I4GL中进行转换是否更容易,或者是否使用程序进行转换,这是一个没有实际意义的问题。我想是后者,所以几年前我写了这个脚本:
#!/usr/bin/env perl

# Convert Informix UNLOAD format to CSV
use strict;
use warnings;
use Text::CSV;
use IO::Wrap;
my $csv = new Text::CSV({ binary => 1 }) or die "Failed to create CSV handle ($!)";
my $dlm = defined $ENV{DBDELIMITER} ? $ENV{DBDELIMITER} : "|";
my $out = wraphandle(\*STDOUT);
my $rgx = qr/((?:[^$dlm]|(?:\\.))*)$dlm/sm;
# $csv->eol("\r\n");
while (my $line = <>)
{
print "1: $line";
MultiLine:
while ($line eq "\\\n" || $line =~ m/[^\\](?:\\\\)*\\$/)
{
my $extra = <>;
last MultiLine unless defined $extra;
$line .= $extra;
}
my @fields = split_unload($line);
$csv->print($out, \@fields);
}
sub split_unload
{
my($line) = @_;
my @fields;
print "$line";
while ($line =~ $rgx)
{
printf "%d: %s\n", scalar(@fields), $1;
push @fields, $1;
}
return @fields;
}

unl2csv - Convert Informix UNLOAD to CSV format
=head1 SYNOPSIS
unl2csv [file ...]
=head1 DESCRIPTION
The unl2csv program converts a file from Informix UNLOAD file format to
the corresponding CSV (comma separated values) format.
The input delimiter is determined by the environment variable
DBDELIMITER, and defaults to the pipe symbol "|".
It is not assumed that each input line is terminated with a delimiter
(there are two variants of the UNLOAD format, one with and one without
the final delimiter).
=head1 EXAMPLES
Input:
10|12|excessive|cost \|of, living|
20|40|bou\\ncing tigger|grrrrrrrr|
Output:
10,12,"excessive","cost |of, living"
20,40,"bou\ncing tigger",grrrrrrrr
=head1 RESTRICTIONS
Since the csv2unl program does not know about binary blob data, it
cannot convert such data into the hex-encoded format that Informix
requires.
It can and does handle text blob data.
=head1 PRE-REQUISITES
Text::CSV_XS

我通过使用Excel progid编写XML来生成4GL代码中的Excel文件(&#34;?mso-application progid = \&#34; Excel.Sheet \&#34;?)因此Excel将其打开。
就像从4GL编写HTML一样,你只需要将HTML代码存档即可。但是使用Excel编写XML。
