symbol not prev. def. _INTRC_OSC 16F88

[MarkR]

Double before config, rest is single
The error message shows two underscores indeed, but when I delete the single underscore before INTRC_OSC_NOCLKOUT in my code then the following message is displayed:
Error[113] C:\XWISP2\TAP.ASM 391 : Symbol not previously defined (INTRC_OSC_NOCLKOUT)

The only working oscillator configs are HS_OSC, XT_OSC, LP_OSC
