SIMSCRIPT II.5 Programming Language

Programming Language Concepts
(normally) conditions in effect at the time they are first encountered, unless these properties are
redefined in the define statements.
All variables that do not appear in a program preamble are local. Local variables can be used both
in subprograms and in main routines. Normally statements can be used in routines to set background
conditions for local variables, but these conditions do not carry over from one routine to another.
Only the last defined normally conditions in the preamble carry over from routine to
routine. Program 2-1 illustrates how normally and define statements are used to specify properties
of local and global variables.
