Posts: 655 		I have a Basic program that contains a line along the lines of:

10 OSCLI "perl <Markdown> <infile>"

where <markdown> is the path to a perl script, and <infile> is the path to a file processed by the Markdown script.

When run in a task window from the basic intepreter invoked by '*basic', the program gets as far as this line, which executes correctly, but the subsequent line is never executed, the program ceases, and I am presented with a star prompt - not Basic's > prompt.

Similarly, when the line is called from a WebJames Baisc cgi script, it kills execution of the script.

So my questions are twofold:
  1. Am I doing something blatently stupidly wrong, here?
  2. If not, is there a workaround, short of learning perl and rewriting my cgi-script in that language?

monkeyson2Please don't let them make me be a monkey butler

Posts: 12380 		It's because you're executing a new program (rather than a module *command).

For what you want to do, I believe you have to use Wimp_StartTask, which can only be done as part of a Wimp application.

SYS "Wimp_Initialise", blah-i-can't-remember
SYS "Wimp_StartTask", "perl <Markdown> <infile>"
SYS "Wimp_Closedown", blah-i-can't-remember
