Your english is fine! A quick web search for the tech manual gives: http://sam.speccy.cz/os_tech/sam_coupe_tech-man_v3-0.pdf Page 35 (page 40 of the pdf) looks like it might be helpful: JEXPT1NUM (0118H) Syntax check/evaluate a numeric expression. During syntax checking an invisible 5-byte form of any literal numbers is inserted. During run time the result of the expression is left on the floating point calculator stack. JEXPTSTR (0116H) Syntax check/evaluate a string expression. See JEXPT1NUM. JEXPTEXPR (0llEH) Syntax check/evaluate an expression. See JEXPT1NUM. These three routines can be useful in extending the Basic interpreter.
