TYPE var[(dim[,dim[,dim]])][,var...] )
PPL utilizes the following data types:
unsigned character (1 byte) 0 = FALSE, non-0 = TRUE
unsigned integer (2 bytes) PCBoard julian date (count of days since 1/1/1900)
Signed long integer for julian date. DDATE is for use with DBase date fields. It holds a long integer for julian dates. When coerced to string type it is in the format CCYYMMDD or 19940527
signed long integer (4 bytes) Range: -2,147,483,648 → +2,147,483,647
signed long integer (4 bytes) Range: -$21,474,836.48 → +$21,474,836.47
far character pointer (4 bytes) NULL is an empty string non-NULL points to a string of some length less than or equal to 256
signed long integer (4 bytes) Count of seconds since midnight
Allows up to 2048 characters per big string (up from 256 for STRING variables) May include CHR(0) characters in the middle of the big string (unlike STRING variables which may not)
Julian date in earth date format Deals with dates formatted YYMM.DD Range: Same as DATE
4-byte floating point number Range: +/-3.4E-38 - +/-3.4E+38 (7-digit precision)
8-byte floating point number Range: +/-1.7E-308 - +/-1.7E+308 (15-digit precision)
4-byte unsigned integer Range: 0 - 4,294,967,295
1-byte unsigned integer Range: 0 - 255
2-byte unsigned integer Range: 0 - 65,535
1-byte signed Integer Range: -128 - 127
2-byte signed integer Range: -32,768 - 32,767
Any type may be assigned to any other type. This is the simplest way to accomplish type conversion. BOOLEAN, DATE, INTEGER, MONEY and TIME are all integer types and may be assigned to each other. Assignment from a larger data type to a smaller data type automatically converts the data to a format suitable for the smaller data type. Conversion to and from STRINGs is dependent on the other data type. DATEs are imported/exported as “MM-DD-YY”. TIMEs are imported/exported as “HH:MM:SS”. MONEYs are imported/exported as “#.##” without embedded dollar signs or commas, and using as many characters as needed to the left of the decimal point. All variables must be declared before use.
