I got this error:
cc> epar combine
ERROR: task `combine' has no param file
But I do have combine.par in my iraf/uparm as follows:

The combine.par file should be in $iraf/noao/imred/ccdred/combine.par, what gets put in your uparm file is essentially what you would see from the 'dpar' command to print the parameters. I suspect there may be a problem with your installation, can you verify the combine.par file exits in the noao$imred/ccdred directory? Does a "show iraf" command return the correct path for the iraf root directory on your machine?
Any chance you have the MSCRED package installed and the combine.par file is missing from that, i.e. you installed the package binaries but not the source? Does 'epar' fail with any other tasks? If you try to execute the COMBINE task are you prompted for the parameters or do you get the same error?
Try an "unlearn combine", or better yet is a new MKIRAF to initialize your uparm directory. If we take your first report literally and you have the combine.par file in your uparm dir, instead of the uparm file written by the CL, that would explain why epar couldn't read it.
In my loginuser.cl file, I have mscred loaded. When I comment it out, it works!
Now I have a new problem. I have:
PACKAGE = ccdred
TASK = zerocombine
input = @zeros1 List of zero level images to combine
(output = Zero1) Output zero level name
(combine= median) Type of combine operation
(reject = ccdclip) Type of rejection
(ccdtype= zero) CCD image type to combine
(process= no) Process images before combining?
(delete = no) Delete input images after combining?
(clobber= no) Clobber existing output image?
(scale = none) Image scaling
(statsec= ) Image section for computing statistics
(nlow = 0) minmax: Number of low pixels to reject
(nhigh = 1) minmax: Number of high pixels to reject
(nkeep = 1) Minimum to keep (pos) or maximum to reject (neg)
(mclip = yes) Use median in sigma clipping algorithms?
(lsigma = 3.) Lower sigma clipping factor
(hsigma = 3.) Upper sigma clipping factor
(rdnoise= 0.) ccdclip: CCD readout noise (electrons)
(gain = EGAIN) ccdclip: CCD gain (electrons/DN)
(snoise = ENOISE) ccdclip: Sensitivity noise (fraction)
(pclip = -0.5) pclip: Percentile clipping parameter
(blank = 0.) Value if there are no pixels
(flpar = no) flush pfile on assign?
(mode = ql)
List of zero level images to combine (@zeros1):
ERROR on line 46: No images to combine
cc> page zeros1
but I do have those two fits files in the same directory.
