When compiling programs with the LXBC command, the statistics in the
LST listing file show the percent of total compiler capacity used. Maximums
can be calculated from the percentages shown.
How to compute memory size required for any application:
Interpreter overhead 6.3K . . . . . . . . . . . . . . .
Program running 13.7K . . . . . . . . . . . . . . . . . .
# of CHAINed programs * 13.7K = ??.? K . . .
# of host records/hour
* Hours offline * bytes/rec =
??.? K . . . . . . .
# of RAM file records for
lookup tables, etc. * bytes/rec =
??.? K . . . . .
Total RAM Required = Sum of the above values
