Top Forums Shell Programming and Scripting Awk: Assigning a variable to be the value of FNR at a certain line Post 302961880 by ThomasP on Saturday 5th of December 2015 03:40:04 PM

Ah yes see that's the problem, the 'overlap' NFR will always be several (100+) lines before the oldte==te2 (energy equilibrium) NFR, because of how the simulation works.

So if the some_var still gets evaluated as =NFR when I print it at the end
f.e. print(some_var) then i'll have the wrong value. On the other hand if it only gets evaluated as being = an integer (a previous NFR in this case) than I'm golden.

An array wouldn't help me since I can't know which line I need, that's the whole point of getting the NFR value at that point.

NAME
plmesh - Plot surface mesh SYNOPSIS
plmesh(x, y, z, nx, ny, opt) DESCRIPTION
Plots a surface mesh within the environment set up by plw3d(3plplot). The surface is defined by the two-dimensional array z[nx][ny], the point z[i][j] being the value of the function at (x[i], y[j]). Note that the points in arrays x and y do not need to be equally spaced, but must be stored in ascending order. The parameter opt controls the way in which the surface is displayed. For further details see the PLplot documentation. Redacted form: plmesh(x, y, z, opt) This function is used in example 11. ARGUMENTS
x (PLFLT *, input) Pointer to set of x coordinate values at which the function is evaluated. y (PLFLT *, input) Pointer to set of y coordinate values at which the function is evaluated. z (PLFLT **, input) Pointer to a vectored two-dimensional array with set of function values. nx (PLINT, input) Number of x values at which function is evaluated. ny (PLINT, input) Number of y values at which function is evaluated. opt (PLINT, input) Determines the way in which the surface is represented: opt=DRAW_LINEX: Lines are drawn showing z as a function of x for each value of y[j]. opt=DRAW_LINEY: Lines are drawn showing z as a function of y for each value of x[i]. opt=DRAW_LINEXY: Network of lines is drawn connecting points at which function is defined.
