Aliases:

&is-digits (&variablename)     &Is-Digits (&variablename)
&&isdigits (&variablename)     &IsDigits (&variablename)
ISDIGITS (&variablename)

Comments:

Signs and decimal points are not considered digits.
A negative numeric type argument value--because of the minus sign--is not considered to be all digits.
The original argument remains unchanged.

Examples:

&IS-DIGITS ("123")        = 1
&IS-DIGITS ("+123")       = 0
&IS-DIGITS ("-123")       = 0
&IS-DIGITS ("123-")       = 0
&IS-DIGITS ("123.")       = 0
&IS-DIGITS (123)          = 1
&IS-DIGITS (-123)         = 0
&IS-DIGITS ("123A")       = 0
&IS-DIGITS ("")           = 0
