2.9.8. Package Initialization |
Packages are often stored in files and read into a CoCoA session using the 'Source' command. When a package is loaded, any function whose name is 'Initialize' will automatically be executed. For example, this feature may be used to print a message or initialized global variables when the package is read into a session. (Note: following this rule, if the first time you you access package PKG is to make an explicit call to the function PKG.Initialize() then the function will be called twice!) |
Example |
Package $example Define Initialize() Print 'CALLED INITIALIZE'; MEMORY.MyVar := 17; EndDefine; EndPackage; CALLED INITIALIZE ------------------------------- MEMORY.MyVar; 17 ------------------------------- |
