Hi everybody,

I have a strange problem with EPICS and CSS boy when I want to use an unsigned 32 bits mask.

I have the following PV:

record(longout, "$(user):FDLMaskSet")

{

field(DTYP ,"asynInt32")

field(OUT  ,"@asyn($(PORT),$(ADDR),$(TIMEOUT))FDL_mask")

field(VAL  ,0xFFFFFFFF)

info(autosaveFields, "VAL")

}

and then in CSS/BOY I am using a "Text Input" with Hex32 format.

This solutions works well with 0xFFFFFF but when I want to add 1bit by writing 0x1FFFFFF I obtain 0x2000000 (Same thing happens for all the values above 0xFFFFFF). 

Then, If I use directly in the epics consoles with dpbf FDLMaskSet 0x1FFFFFF it works well.

I did try with bo, ao and also using the RVAL long value instead, but I get the same problem.

Actually I am using 32 boolean buttons with different bit value, but It would be much simpler to change it using hexadecimal value.
