PSL Data Types and Objects

PSL has five data types:

• integer

• hexadecimal literal

• float

• string 

• list

All five types are represented internally as character strings. The following table lists the PSL data types.

Data Type	Example	Representation
integer	3	"3"
float	4.5	"4.5"
string	"abc"	"abc"
list	[ 1, 2, 3 ]	"1\n3\n5"
Note: “\n” is the new-line character.

Variables and values are interpreted as either strings or numbers, whichever is appropriate to the context. A scalar (integer or float) is interpreted as true in the Boolean sense if it is not a null string or 0. Booleans returned by operators are 1 for true and 0 or “” (the null string) for false.
