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: LaserJet279 J1953 Examples of invalid alphanumeric variables include: 279LaserJet (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: 0.123456 -123.456 +657000 2468. Examples of invalid numeric variables include: .123456 (The decimal point must be preceded by at least 1 digit) -123.45.6 (Only 1 decimal point is allowed in a numeric variable) +657,000 (Commas are not allowed in numeric variables) EN PJL Command Syntax and Format 2-7
