Synopsis
Official Name: RclVarSym
BCALL Address: 4AE3
Recalls the value of a TI-OS variable.
Inputs
- OP1 = Name of variable
Outputs
- OP1 = Contents of Variable
- possibly others, please add if known
Registers Destroyed
Unknown
Example
B_CALL ZeroOP1 ;Reset OP1 ld hl,op1+1 ;have hl point to where the name should be stored ld (hl),'H' ;load the name into op1+1 B_CALL RclVarSym ;store the value into op1 (in standard TI-OS floating point decimal form)
Comments
This routine is used to recall TI-OS variables, such a 'A' or 'H' or other single letter varibales, but might be able to be used in recalling different types of variables. Once more doccumentation is found, it will be added.
