07962: THE 'FREE MEMORY' SUBROUTINE

There is no BASIC command 'FRE' in the Spectrum but there is a subroutine for performing such a task. An estimate of the amount of free space can be found at any time by using 'PRINT 65536-USR 7962'.
Output
BC | STKEND+80-SP (free space * -1)
FREE_MEM | 07962 | LD BC,0 | Do not allow any overhead.
| 07965 | CALL TEST_ROOM | Make the test and pass the result to the BC register before returning.
| 07968 | LD B,H
| 07969 | LD C,L
| 07970 | RET
