在 Powershell 中编译 Micro Focus Net Express 5.1 Cobol

Question

我希望有人可以帮助我在 Powershell 中编写 COBOL MF Net Express 5.1 编译命令。我有原始批处理脚本中使用的命令。我目前正在 Powershell 中将其作为构建脚本进行改造。

COBOL.EXE "%%inFile%%" OUTDD NOERRQ NOFLAGQ NOQUERY noALTER noanim nobound checkdiv COMP errlist list() FASTLINK omf"gnt" perform-type"osvs" SCHEDULER TARGET"PENTIUM" noTRUNC vsc2(1) listpath"","%%OUTPUT%%";,;,;

我将其转换为 Powershell 的尝试是这样的：

$cobolExe = ".\COBOL.EXE"
$expression = "& $cobolExe `"$($inputfile)`" OUTDD NOERRQ NOFLAGQ NOQUERY noALTER noanim nobound checkdiv COMP errlist list() FASTLINK omf`"gnt`" perform-type`"osvs`" SCHEDULER TARGET`"PENTIUM`" noTRUNC vsc2(1) listpath`"`", `"$binPath\`";,;,;"
Invoke-Expression $expression

Invoke-Expression: 
Line |
   1 |  Invoke-Expression $expression
     |  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     | At line:1 char:97 + … GQ NOQUERY noALTER noanim nobound checkdiv COMP errlist list() FASTLI … +                                                                ~
An expression was expected after '('.  At line:1
     | char:221 + … NTIUM" noTRUNC vsc2(1) listpath"", "C:\dev\dimensions\test\bin\";,;,; +                                                                     ~
Missing expression after unary operator ','.  At line:1
     | char:223 + … NTIUM" noTRUNC vsc2(1) listpath"", "C:\dev\dimensions\test\bin\";,;,; +                                                                       ~
Missing expression after unary operator ','.

我成功地使用了 CBLLINK.EXE，但它不需要那么多参数。

$cobolFile = "$Path\cobol.dir"
$cbllinkExe = ".\CBLLINK.EXE"

$expression = "$cbllinkExe -s -o$($outputFile) `"$($inputFile)`" adis adisinit adiskey -u`"$cobolFile`""
Invoke-Expression $expression

有哪位大神能指教一下，不胜感激。如果我可以提供其他任何东西，请告诉我？

通过 PowerShell 调用外部 exe's/cmd 需要特别注意。这是一个有据可查的事情。

查看 Microsoft 和其他公司的详细信息：---

PowerShell: Running Executables

The Call Operator &

# Example:
& 'C:\Program Files\Windows Media Player\wmplayer.exe' "c:\videos\my home video.avi" /fullscreen

Things can get tricky when an external command has a lot of parameters or there are spaces in the arguments or paths!

With spaces you have to nest Quotation marks and the result it is not always clear!

In this case it is better to separate everything like so:

$CMD = 'SuperApp.exe'
$arg1 = 'filename1'
$arg2 = '-someswitch'
$arg3 = 'C:\documents and settings\user\desktop\some other file.txt'
$arg4 = '-yetanotherswitch'

& $CMD $arg1 $arg2 $arg3 $arg4

# or same like that:
$AllArgs = @('filename1', '-someswitch', 'C:\documents and settings\user\desktop\some other file.txt', '-yetanotherswitch')
& 'SuperApp.exe' $AllArgs

cmd /c - Using the old cmd shell ** This method should no longer be used with V3

Why: Bypasses PowerShell and runs the command from a cmd shell. Often times used with a DIR which runs faster in the cmd shell than in PowerShell (NOTE: This was an issue with PowerShell v2 and its use of .Net 2.0, this is not an issue with V3).

Details: Opens a CMD prompt from within powershell and then executes the command and returns the text of that command. The /c tells CMD that it should terminate after the command has completed. There is little to no reason to use this with V3.

# Example:
#runs DIR from a cmd shell, DIR in PowerShell is an alias to GCI. This will return the directory listing as a string but returns much faster than a GCI
cmd /c dir c:\windows

Using Windows PowerShell to run old command line tools (and their weirdest parameters)

Solution 2A: Use CMD /C

As with the first problem, you can run CMD.EXE itself and pass your command and its parameters in quotes. Efficiency aside, this will work fine, since PowerShell will not try to parse the string in quotes.

CMD.EXE /C "ICACLS.EXE C:TEST /GRANT USERS:(F)"

<#
# Results

processed file: C:TEST
Successfully processed 1 files; Failed processing 0 files
#>
