The problem I'm having is nestling the ` ` to evaluate something. How can you use an evaluate within an evaluate?

echo "../mhisto `f=xa.txt;s=` some commands in here ` ` "
You can use the escape character '\' (backward slash) before the grave-accent character in order to have nesting (i.e) "\`"

NAME
glEvalPoint1, glEvalPoint2 - generate and evaluate a single point in a mesh C SPECIFICATION
void glEvalPoint1( GLint i ) void glEvalPoint2( GLint i, GLint j ) PARAMETERS
i Specifies the integer value for grid domain variable i. j Specifies the integer value for grid domain variable j (glEvalPoint2 only). DESCRIPTION
glMapGrid and glEvalMesh are used in tandem to efficiently generate and evaluate a series of evenly spaced map domain values. glEvalPoint can be used to evaluate a single grid point in the same gridspace that is traversed by glEvalMesh. Calling glEvalPoint1 is equivalent to calling glEvalCoord1( i./u+u1 ); where /u=(u2-u1)/n and n, u1, and u2 are the arguments to the most recent glMapGrid1 command. The one absolute numeric requirement is that if i=n, then the value computed from i./u+u1 is exactly u2. In the two-dimensional case, glEvalPoint2, let /u=(u2-u1)/n /v=(v2-v1)/m, where n, u1, u2, m, v1, and v2 are the arguments to the most recent glMapGrid2 command. Then the glEvalPoint2 command is equivalent to calling glEvalCoord2( i./u+u1, j./v+v1 ); The only absolute numeric requirements are that if i=n, then the value computed from i./u+u1 is exactly u2, and if j=m, then the value computed from i./v+v1 is exactly v2.
