Top Forums Shell Programming and Scripting How to extract the individual element of array where array is assigned to another variable? Post 303045831 by sea on Tuesday 14th of April 2020 02:03:16 PM

Hi

You would have better chances with your code, if you would save lists (var="1 2 3")in the file.txt, rather than arrays.
In which case, your code would work just fine - as it is right now.

As a 2nd note, * and @ behave differently for arrays.
Though, you'll get only the first value of an array shown, with this method.

Hope this helps

GLARRAYELEMENT(3G)														GLARRAYELEMENT(3G)

NAME
glArrayElement - render a vertex using the specified vertex array element C SPECIFICATION
void glArrayElement( GLint i ) PARAMETERS
i Specifies an index into the enabled vertex data arrays. DESCRIPTION
glArrayElement commands are used within glBegin/glEnd pairs to specify vertex and attribute data for point, line, and polygon primitives. If GL_VERTEX_ARRAY is enabled when glArrayElement is called, a single vertex is drawn, using vertex and attribute data taken from location i of the enabled arrays. If GL_VERTEX_ARRAY is not enabled, no drawing occurs but the attributes corresponding to the enabled arrays are modified. Use glArrayElement to construct primitives by indexing vertex data, rather than by streaming through arrays of data in first-to-last order. Because each call specifies only a single vertex, it is possible to explicitly specify per-primitive attributes such as a single normal per individual triangle. Changes made to array data between the execution of glBegin and the corresponding execution of glEnd may affect calls to glArrayElement that are made within the same glBegin/glEnd period in non-sequential ways. That is, a call to glArrayElement that precedes a change to array data may access the changed data, and a call that follows a change to array data may access original data. NOTES
glArrayElement is available only if the GL version is 1.1 or greater. glArrayElement is included in display lists. If glArrayElement is entered into a display list, the necessary array data (determined by the array pointers and enables) is also entered into the display list. Because the array pointers and enables are client-side state, their val- ues affect display lists when the lists are created, not when the lists are executed. SEE ALSO
