Detailed Description

Generate and return a logical vector whose elements are .true. if and only if the corresponding characters in the input string belong to the uppercase English alphabet ALPHA_UPPER_VEC_SK.

Parameters

[in]

str

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

Returns

StrIsLower : The output vector of (rank 1) of type logical of default kind LK, of the same size as the length of the input str whose elements are .true. if and only if the corresponding characters in the input string belong to the lowercase English alphabet, otherwise they are .false..

Possible calling interfaces ⛓

use pm_kind, only: LK
use pm_strASCII, only: isStrLower
logical(LK) :: CaseIsLower(len(str,IK))
 
StrIsLower = isStrLower(str)

Remarks

The procedures under discussion are pure.
