1.157.5 Stream: built ins

fileIn

File in the contents of the receiver. During a file in operation, global variables (starting with an uppercase letter) that are not declared don’t yield an ‘unknown variable’ error. Instead, they are defined as nil in the ‘Undeclared’ dictionary (a global variable residing in Smalltalk). As soon as you add the variable to a namespace (for example by creating a class) the Association will be removed from Undeclared and reused in the namespace, so that the old references will automagically point to the new value.

fileInLine: lineNum file: aFile at: charPosInt

fileInLine: lineNum fileName: aString at: charPosInt

Private - Much like a preprocessor #line directive; it is used internally by #fileIn, and explicitly by the Emacs Smalltalk mode.
