I am studying simple EMS script as below.
This is quiet simple script, but there are always EMS errors in the EDD file after complete the run.
The variable 'Var1' is global variable, and I test various EMS calling points for the initialization(see IDF script).
However, the EDD file always tell me that the 'Var1' is not initialized.
How can I fix this?
PROGRAM1,Line 1,IF VAR1 == 0, * Error: EvaluateExpression: Variable = 'VAR1' used in expression has not been initialized! * , During Warmup, Occurrence info=RUN PERIOD 1, 01/01 00:00 - 00:05
PROGRAM1,Line 6,SET VAR1 = VAR1+1, * Error: EvaluateExpression: Variable = 'VAR1' used in expression has not been initialized! * , During Warmup, Occurrence info=RUN PERIOD 1, 01/01 00:00 - 00:05
