E r g e b n i s / R e s u l t
The routine returns true if s contains only alphabetic characters.
This is similar to the function
OISALPHA, but for a multiple character string.
B e s c h r e i b u n g / D e s c r i p t i o n
ALPHABET returns a TRUE if s is a string that consists of characters within the ranges A – Z or a – z.
The routine returns FALSE if s does not satisfy the test condition.
S y n t a x
Code:
value = call ('ALPHABET' , s) P a r a m e t e r
s - String to test
R e t u r n s
TRUE, if the string consits of alphabetic characters, FALSE otherwise
B e i s p i e l / E x a m p l e
Code:
attach 'STRFUNC'
put call ('ALPHABET' , 'ABCDE') ! returns true, as it's alphabetic
put call ('ALPHABET' , 'ABCD9') ! returns false, as it's not alphabetic
detach 'STRFUNC'
