superphil06 0:539b0fc9d536 13 * Module : HTML.C
superphil06 0:539b0fc9d536 14 * Function : contains functions to operate between HTML files and SC12
superphil06 0:539b0fc9d536 15 * Cgi Interface. It read Html files, copy it into memory
superphil06 0:539b0fc9d536 16 * block and save positions of '^VARDEF[x]' entry in var_field
superphil06 0:539b0fc9d536 17 * struct to insert dynamtic code int the static file.
superphil06 0:539b0fc9d536 18
superphil06 0:539b0fc9d536 19 By Example:
superphil06 0:539b0fc9d536 20 On the flash exists the following htm file (a:\exp.htm):

superphil06 0:539b0fc9d536 25 The first Dynamic code/text ^VARDEF[0] = 32 <BR>
superphil06 0:539b0fc9d536 26 And now the Dynamic code/text ^VARDEF[1] = 3 <BR>
