array of strings

Hi
I need a better idea to implementing following in my code.

I need to store 80 long strings that will be used to display one by one in my GUI application. now i am storing those 80 long string in following two dimentational array.

uchar vpn_alm_long_str[MAX_ALARM][1024]={ }

each index will be an string index .
all strings would be defined static and this variable would be a global one .
so the issues that i can forsee

some issue with where this will be stored like in data segment (but don't know exactly the issue?/)
does not look good to store such big data structure in memnory when they are not going to be used always.
Insetad , if we can write all these strings in a file in a special format , and on run time we extract these string from that file , that sounds a good idea .
at least that file would be stored on disk not in the memory , and that would be brought in the memory only when it will be required to read and even that would be the only a string not the complete file ..

pls any other idea??

GLSHADERSOURCE(3G)						    OpenGL 3.3							GLSHADERSOURCE(3G)

NAME
glShaderSource - Replaces the source code in a shader object C SPECIFICATION
void glShaderSource(GLuint shader, GLsizei count, const GLchar **string, const GLint *length); PARAMETERS
shader Specifies the handle of the shader object whose source code is to be replaced. count Specifies the number of elements in the string and length arrays. string Specifies an array of pointers to strings containing the source code to be loaded into the shader. length Specifies an array of string lengths. DESCRIPTION
glShaderSource sets the source code in shader to the source code in the array of strings specified by string. Any source code previously stored in the shader object is completely replaced. The number of strings in the array is specified by count. If length is NULL, each string is assumed to be null terminated. If length is a value other than NULL, it points to an array containing a string length for each of the corresponding elements of string. Each element in the length array may contain the length of the corresponding string (the null character is not counted as part of the string length) or a value less than 0 to indicate that the string is null terminated. The source code strings are not scanned or parsed at this time; they are simply copied into the specified shader object. NOTES
OpenGL copies the shader source code strings when glShaderSource is called, so an application may free its copy of the source code strings immediately after the function returns. ERRORS
GL_INVALID_VALUE is generated if shader is not a value generated by OpenGL. GL_INVALID_OPERATION is generated if shader is not a shader object. GL_INVALID_VALUE is generated if count is less than 0. ASSOCIATED GETS
