The compile switches are set in RECOMX.BP by means of a single bit field, CMPSWITCHES. So locate the RECOMX.BP source file, then locate that variable and change its initial value (either in the MAP statement, or in an assignment statement).
The switch value for /L (aka /LF) is 524288 (&h80000).
So, for example, if the previous value was 256, change it to 524288+256=524544 (or &h80100).
Then recompile RECOMX. (If you were using RECOMX.LIT instead of RECOMX.RUN, then just rename the new RECOMX.RUN to RECOMX.LIT).
Then use it to recompile your programs.
(I moved this topic to the Program Development forum, as it seems to relate there better than here.)
