Byte Level Handling
Posted: Mon Jul 13, 2026 2:02 pmHi There
Iam trying to use the STOBM, RCLBM & X<>BM byte functions provided by Angel Martin's RAMPAGE module. Iam using ZENROM SYNTEXT mechanism to code the required byte/register addresses. The STOBM function seems to work fine but the RCLBM does not decode back into decimal (X) as shown below:
ABS REG# B6 B5 B4 B3 B2 B1 B0
0CEh 206d 00 00 00 44 43 42 41
To reacall byte 0 from reg# 0CE I enter 00 CE
XEQ RCLBM, X = 577d (241h)
To reacall byte 1 from reg# 0CE I enter 10 CE
XEQ RCLBM, X = 1090d (442h)
To reacall byte 2 from reg# 0CE I enter 20 CE
XEQ RCLBM, X = 579d (2432h)
To reacall byte 3 from reg# 0CE I enter 30 CE
XEQ RCLBM, X = 580d (244h)
Why am I not getting the values 65, 66, 67 & 68 respectively in X! Am I doing something silly or do have brain fog?
