Supported Variable Types

PeopleCode supports these types of variables:

Term	Definition
User-defined variables	These variable names are preceded by an & character wherever they appear in a program. Variable names can be 1 to 1000 characters, consisting of letters A through Z and a through z, digits 0 through 9, and characters #, @, $, and _.
System variables	System variables provide access to system information. System variables have a prefix of the % character rather than the & character. Use these variables wherever you can use a constant, passing them as parameters to functions or assigning their values to fields or to temporary variables.
