Re: load file defined
Hello Andrea,
have a look at this. Code:
{ rem input in drafting the macro Macrostart: v macro v Parameter file_exists "path/filename" Global variable: gv_file_existent end rem } DEFINE file_exists PARAMETER File_1 LOCAL Default_file LET Default_file "path/default_filename" {* Change *} LET gv_file_existent 0 TRAP_ERROR LOAD File_1 IF (CHECK_ERROR) DISPLAY("File "+File_1+" not existent. Load Default File? Yes= any key | No= ESC ") LOAD Default_file ELSE LET gv_file_existent 1 END_IF END_DEFINE Last edited by Friedly; 11-20-2015 at 12:54 PM. |

Re: load file defined
You may also consider SEARCH command. With SEARCH you may enter different directories from where the LOAD command will try to find out and load the file to LOAD.
Ex: LOAD "myfile" will try to locate and load "myfile" in each ordered directories specified by SEARCH. To know about your SEARCH settings, let use EDIT_ENVIRONMENT. |
