| jbe/bsw@9 | 10 This function is used to insert a script into the active slot. |
| jbe/bsw@0 | 11 |
| jbe/bsw@11 | 12 WARNING: If the script contains two closing square brackets directly followed by a greater-than sign, it will be rejected to avoid ambiguity related to HTML vs. XML parsing. Additional space characters can be added within the program code to avoid occurrence of the character sequence. The function encode.json{...} encodes all string literals in a way that the sequence is not contained. |
