Detailed Description

Generate and return .true. if the input (single) character is a digit or an uppercase or lowercase English alphabet ALPHA_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 len = 1.

Returns

charIsAlphaNum : 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 belongs to the set of English digits or English alphabets (lowercase or uppercase), otherwise it is .false..

Possible calling interfaces ⛓

use pm_kind, only: LK
use pm_strASCII, only: isCharAlphaNum
logical(LK) :: charIsAlphaNum
 
charIsAlphaNum = isCharAlphaNum(chr)

Remarks

The procedures under discussion are pure.
