I have one steptype in which during Edit, the new variable has been created. I also saved that sequence. If I close that sequence file with that steptype and reopen the same sequence, the variable created last time was not there. I think these variable are not getting stored with sequence. The steptype building block is created in CVI. Those edit time variable creation is done by means of using “TS_PropOption_InsertIfMissing” functions in CVI. Can you please tell us is there any CVI functions to create variable during edit time and to be saved with the sequence.??
