not enough space for dimensional arrays in famicom basic using mmc5 mod

[777]

in the familybasic emulator by TAKEDA, toshiya ,i have a problem with dimensional arrays. if i try and add more than 63 dimensional strings, it gives me a ov error. its not running out of memory but i think its not using all the extra ram for variables. is there a way around this? like moving the ramtop or basic allocation space, etc? say, with a poke? ive noticed that if there is no program in the memory, this problem doesnt happen

The CLEAR command has that effect when passing an address as an argument. Check the CALL command in the manual.
