Detailed Description

Generate and return .true. if the input single character contains an lowercase English alphabet ALPHA_LOWER_VEC_SK.

Parameters

[in]

chr

: The input scalar or array of arbitrary rank of type character of kind any supported by the processor (e.g., SK, SKA, SKD , or SKU) of length 1.

Returns

charIsLower : The output scalar or array of the same shape as the input chr of type logical of default kind LK whose value is .true. corresponding to each element of the input chr if the element is an lowercase English letter, otherwise it is .false..

Possible calling interfaces ⛓

use pm_kind, only: LK
use pm_strASCII, only: isCharLower
logical(LK) :: charIsLower
 
charIsLower = isCharLower(chr)

Remarks

The procedures under discussion are pure.

The procedures under discussion are elemental.
