Types of Variables
PJL uses alphanumeric variables, numeric variables, and
strings. The following explains the three types of variables
and their ranges.
Alphanumeric variables. Any combination of letters
and digits, with the stipulation that the first character
always must be a letter. Letters consist of the uppercase
letters (Roman-8 characters 65 through 90) and
lowercase letters (97 through 122). Digits consist of
numbers 0 through 9 (characters 48 through 57).
Examples of valid alphanumeric variables include:

J1953
Examples of invalid alphanumeric variables include:

(Alphanumeric variables must begin with a letter)
J 1953
(Space characters [ASCII 32] are not allowed in
alphanumeric variables)
Numeric variables. Any number consisting of digits,
with one optional decimal point and an optional + or –
sign preceding the first digit. Only one decimal point
may be used, and it must be placed somewhere after the
first digit. Digits are not required after the decimal point.
Examples of valid numeric variables include:
