pm_sysShell::isShellCMD Interface Reference

Generate and return .true. if the runtime system shell is Windows CMD. More...

Detailed Description

Generate and return .true. if the runtime system shell is Windows CMD.

Refer to the documentation details of shell_type for information on what system shells are available on what operating systems.
The procedures of this generic interface serve as a shortcut to the cmd component of shellis_type.

Parameters

[out]	failed	: The output scalar logical of default kind LK that is .true. if and only if an error occurs while inferring the system shell type. (optional. If missing and a runtime error occurs, the program will halt by calling error stop.)
[in,out]	errmsg	: The input/output scalar character of default kind SK of arbitrary length type parameter. If an error occurs, errmsg will be set to a descriptive message about the nature of the runtime error. A length of LEN_IOMSG characters is likely sufficient to capture most error messages in full. (optional. If missing, no error message will be output. Its presence is relevant only if failed is also present.)

Returns

shellIsCMD : The output scalar logical of default kind LK. It is .true. if and only if the runtime system shell is Windows-based (e.g., CMD, PowerShell).

Possible calling interfaces ⛓

use pm_sysShell, only: isShellCMD
use pm_kind, only: LK
logical(LK) :: failed
logical(LK) :: shellIsCMD
character(255, SK) :: errmsg = SK_""
 
shellIsCMD = isShellCMD()
shellIsCMD = isShellCMD(failed)
shellIsCMD = isShellCMD(failed, errmsg)

Remarks

The procedures under discussion are impure.

Example usage ⛓

program example
 
    use pm_kind, only: LK, IK, SK
    use pm_io, only: display_type
    use pm_sysShell, only: isShellCMD
 
    implicit none
 
    character(255, SK)  :: errmsg = SK_""
    logical(LK)         :: failed
 
    type(display_type)  :: disp
    disp = display_type(file = "main.out.F90")
 
    call disp%skip()
    call disp%show("isShellCMD()")
    call disp%show( isShellCMD() )
    call disp%skip()
 
    call disp%skip()
    call disp%show("isShellCMD(failed)")
    call disp%show( isShellCMD(failed) )
    call disp%show("failed")
    call disp%show( failed )
    call disp%skip()
 
    call disp%skip()
    call disp%show("isShellCMD(failed, errmsg)")
    call disp%show( isShellCMD(failed, errmsg) )
    call disp%show("failed")
    call disp%show( failed )
    call disp%show("trim(errmsg)")
    call disp%show( trim(errmsg) , deliml = SK_"""" )
    call disp%skip()
