For your questions, why a[$1] didn't throw errors because if any variable is NOT initialized in awk and we are using it in any condition or etc then its value will be considered as NULL, hence NO ERRORS in it.
I am adding a detailed level of explanation here for my solution above:

GLGETACTIVEUNIFORMNA(3G) OpenGL 3.3 GLGETACTIVEUNIFORMNA(3G)NAME
glGetActiveUniformName - query the name of an active uniform
C SPECIFICATION
void glGetActiveUniformName(GLuint program, GLuint uniformIndex, GLsizei bufSize, GLsizei *length, GLchar *uniformName);
PARAMETERS
program
Specifies the program containing the active uniform index uniformIndex.
uniformIndex
Specifies the index of the active uniform whose name to query.
bufSize
Specifies the size of the buffer, in units of GLchar, of the buffer whose address is specified in uniformName.
length
Specifies the address of a variable that will receive the number of characters that were or would have been written to the buffer
addressed by uniformName.
uniformName
Specifies the address of a buffer into which the GL will place the name of the active uniform at uniformIndex within program.
DESCRIPTION
glGetActiveUniformName returns the name of the active uniform at uniformIndex within program. If uniformName is not NULL, up to bufSize
characters (including a nul-terminator) will be written into the array whose address is specified by uniformName. If length is not NULL,
the number of characters that were (or would have been) written into uniformName (not including the nul-terminator) will be placed in the
variable whose address is specified in length. If length is NULL, no length is returned. The length of the longest uniform name in program
is given by the value of GL_ACTIVE_UNIFORM_MAX_LENGTH, which can be queried with glGetProgram().
If glGetActiveUniformName is not successful, nothing is written to length or uniformName.
program must be the name of a program for which the command glLinkProgram() has been issued in the past. It is not necessary for program to
have been linked successfully. The link could have failed because the number of active uniforms exceeded the limit.
uniformIndex must be an active uniform index of the program program, in the range zero to GL_ACTIVE_UNIFORMS - 1. The value of
GL_ACTIVE_UNIFORMS can be queried with glGetProgram().
ERRORS
GL_INVALID_VALUE is generated if uniformIndex is greater than or equal to the value of GL_ACTIVE_UNIFORMS.
GL_INVALID_VALUE is generated if bufSize is negative.
GL_INVALID_VALUE is generated if program is not the name of a program object for which glLinkProgram() has been issued.
