Function Block
InstallShield 2022 ยป InstallScript Language Reference
Project:This information applies to InstallScript projects.
All functions that have been declared with a prototype statement must be defined in the function block, which follows the keyword endprogram in a setup script. Additional global data declarations may be made in the function block, either between the endprogram statement and the first function declaration or between function declarations. However, data declared in the function block is visible only to functions that are defined after the data declaration.
