Tcsh command for assigning output of awk to variable

Hi I have a text file with 2 values and I am trying to assign each value to a variable and then write those to text files.

So if the textfile is data.txt with 2 values x and y

I want to assign mean=x, and stdev=y and then write these out in text files alongwith the id ($id has already been set earlier on in a larger script).

say
Code:
 echo $mean $id > mean.$id.text
     echo $stdev $id > stdev.$id.text

later on I want to go through and concatenate all the mean values for all id's into 1 file and similarly create another one for stdev.
so far I tried this (after looking through various threads)---
Code:
        mean=$( awk '{ print $1}' data.txt)
	echo $mean $id  > mean.txt

doesn't work, says illegal variable name.



thanks for any help.

NAME
MPSMatrixUnaryKernel SYNOPSIS
#import <MPSMatrixTypes.h> Inherits MPSKernel. Inherited by MPSMatrixDecompositionCholesky, MPSMatrixDecompositionLU, MPSMatrixFindTopK, MPSMatrixNeuron, and MPSMatrixSoftMax. Properties MTLOrigin sourceMatrixOrigin MTLOrigin resultMatrixOrigin NSUInteger batchStart NSUInteger batchSize Additional Inherited Members Detailed Description This depends on Metal.framework A MPSMatrixUnaryKernel consumes one MPSMatrix and produces one MPSMatrix. Property Documentation - batchSize [read], [write], [nonatomic], [assign] The number of matrices in the batch to process. This property is modifiable and by default allows all matrices available at encoding time to be processed. If a single matrix should be processed set this value to 1. - batchStart [read], [write], [nonatomic], [assign] The index of the first matrix in the batch. This property is modifiable and defaults to 0 at initialization time. If batch processing should begin at a different matrix this value should be modified prior to encoding the kernel. - resultMatrixOrigin [read], [write], [nonatomic], [assign] The origin, relative to [0, 0] in the result matrix, at which to start writing results. This property is modifiable and defaults to [0, 0] at initialization time. If a different origin is desired then this should be modified prior to encoding the kernel. The z value must be 0. - sourceMatrixOrigin [read], [write], [nonatomic], [assign] The origin, relative to [0, 0] in the source matrix, at which to start reading values. This property is modifiable and defaults to [0, 0] at initialization time. If a different origin is desired then this should be modified prior to encoding the kernel. The z value must be 0.
