Whitespace

The following guidelines apply to whitespace:

• Insert blank lines between lines of executable code to make code easier to read. For example, insert blank lines between segments of code (e.g., after the initialization of variables, before and after nested blocks, etc.).

• Sections of code can be indented to enhance the format of the code (e.g., If/Else conditions).

• Whitespace can consist of either <space> or <tab> characters.

• Use whitespace around the assignment operator in set and type statements and around binary operators in expressions.

• Commands must be followed by one space and an expression, or two spaces or end-of-line (if argumentless).

• Commands followed by post-conditional arguments must be followed by a colon with no whitespace.

• Argumentless commands (e.g., FOR, ELSE, IF QUIT) with one space will compile with a warning.

• The following are whitespace independent:

• Array subscripts

• Command position on the line

• Command, parameter, and subscript separator (,)

• Formal and actual parameter expressions

• Parentheses

• Property and method references

• Relational and Boolean operators (<>[]!&#*+-'=)

Example

type RecordDEP dep = Db.getRecord(“DEP”,”CID=:CID”)

type String TYPE = dep.type

type Number JOB = %ProcessID

type RecordTEST tmp

if 'Db.isDefined("TEST","JOB = :JOB, TYPE = :TYPE") do {

      set tmp = Class.new("RecordTEST")

      set tmp.job  = %ProcessID

      set tmp.type = dep.type

}

else  set tmp = Db.getRecord("TEST","JOB=:JOB, TYPE=:TYPE")

set tmp.totbal = tmp.totbal + dep.bal

do tmp.save()

*CID must be defined prior to the getRecord statement.
