Code:
When compiling the program in MCS, have you selected the 16F628A in the device drop-down box.
Yes, Darrel. Both Drop Down boxes have 16F628A selected. The MCS & the EPICWin. That's what's funny. Everything programs except DATA & EEPROM commands. It has programed the DATA or EEPROM for other chips in the past. I know it has programmed the 16F628 chip because I programmed one yesterday. I have a bread board sitting in front of me, using your large number program, counting up right now.

Darrel, I replaced the power supply with two 9 Volt batteries. It gave the same Data Error message. Maybe I'll rewrite the 16F628A file to the EPIC directory. It might be corrupted. I looked at it and it looked OK. Is there a setting or a file in MPASM that has to be set or could be corrupted?

Thank for the time and effort.
